I have recently tried migrating our Trac 0.12 system over to red mine 2.1.4

The rake file runs and says transfers 147/147 tickets successfully.

When I log in I can see my tickets listed however when I click on one it just sends me to "internal server error page"?

Can anyone please help here?

Hey everyone,

I found out what the problem is: dates in trac 0.12.3 are stored as microseconds from epoch. Function signature is[, microseconds]).

As attachment, you can find a svn diff that correct this bug. I have never developed with ruby before today so it may be a very dirty fix. I'm quite sure that it won't work with prior trac version that does not store dates as microseconds (I think prior to 0.12).
