Redmine

But I let a lot of people try it, all of them reproduct this error:

Browse this page ok.
However, a click on PDF export, first appeared a very long wait, and then throw 500 internal error.

Debian           Iceweasel/3.5.8 (like Firefox/3.5.8)
Windows XP      IE6 
Windows 7       IE8

I can confirm this bug, although I cannot confirm it on the redmine.org page, but it happens on my 0.9.3 production version. It does NOT happen when using English language. But it does happen with certain languages.
An example is the Slovenian language. Here is some code from my sl.yml:

  ...
  general_lang_name: 'Slovenščina'
  general_csv_separator: ','
  general_csv_decimal_separator: '.'
  general_csv_encoding: ISO-8859-1
  general_pdf_encoding: ISO-8859-1
  general_first_day_of_week: '1'
  ...

The error can always be reproduced, the exact error as stated in my Redmine log is:

Any information on this?

• The error can always be reprodued in redmine 0.8.7 production.
• what is more,this error is not always occur, it will only appear in the case of the issue is too long.
• When this error occurs, CUP will reach 100%.

Oh, I'm sorry.
It should be the CPU rather than the CUP

Upon further inspection there seems to be a problem with some of the language templates and this method:

 def number_to_human_size(number, *args)

It seems the method is supposed to take a number as an argument and return the text in the appropriate human readable form (ie. 356.56 KB). But instead it somehow returns a Float insted, without converting it to human text form. Thus the methos gsub is not found for type Float.

Thanks for your efforts! :)
But This page (http://www.redmine.org/issues/408) has no attachments, the 500 internal error still occurs.
I think your solution is another bug, rather than I pointed out that the bug.
On this question, I also think that too long issues description lead to error occurs.

once one issue with too long description (In particular, there is a particularly long line) lead to this error,
then I split the long line issue description information into two lines, it work well.

I've encountered the same "defect" using redmine 0.9.3 stable with english. I can replicate on my server irrespective of the issue size or with/without attachments.

After sometime I decided to upgrade to the latest in the svn repository. I backed up my database.yml and email.yml. I wiped the location clean and performed an svn checkout. I'm now on Redmine 0.9.3.devel.3668 (MySQL) and I'm still seeing the issue. I'm now wondering if there is some configuration setting in the database (i have no idea, just guessing) that is making this happen.

I have a different server running Redmine 0.9.3.devel.3608 (MySQL) and I'm not seeing the issue there.

Thanks for looking into this.

Steps：

1. browse http://www.redmine.org/issues/408
2. Click on link to PDF Export

Error information:
[...]

Key points:

The browser's preferred language set to Chinese will appear in this exception.
However, the browser's preferred language set to English will not appear.

I am unable to reproduce using any language on trunk r3696 nor on redmine.org

But, once I set browser preferred language to Chinese, browse http://www.redmine.org/issues/408 , click PDF export, internal error could occur. However, set browser preferred language to english, it could not occur.

Ah ok, doing traditional chinese and using that exact issue #408 I am able to reproduce. Does not error with any other random issue I checked.

I think this is the pdf export function bug. What's more, only too long issue can lead to this exception.
I once encountered similar problems:

There is a long long issue description inline. Once I click pdf export, it occur internal error. In addition, the CPU up to 100%。
then, I split the long line issue description information into two lines, it work well.

sl.yml.diff has committed r4004 #6009.

source:trunk/config/locales/sl.yml@3610#L128
"general_pdf_encoding": UFT-8

Guess it is not up to date to latest stable, far from that (no subtasking support), so that could take a while =)

Thank you for your hard work~
