Currently I'm unable to open tickets with Firefox on Linux and Windows as well as Konqueror on Linux. A JavaScript mades the ticket creation not usable. Therefore I edited the ticket step by step with Internet Explorer.

I think the Problem is the preview functionality. It Ends with a preview in a preview in a preview …

Duplicate of #10676.

Make sure to uninstall TracGit when you upgrade to 1.0 since the functionality has been integrated into Trac. See TracGit for more info.

Were the changes made back into 0.12 branch?

[Ryan J Ollos]

The 0.12 branch for the ​th:GitPlugin is not maintained by the Trac development team. I doubt the changes were backported to that plugin. The 0.12 branch of Trac does not support Git. You'll need to upgrade to Trac 1.0 to get the Git support provided by Trac.

[joachim.langenbach@…]

Seems to be not backported into 0.12 branch. Fixed it in our debian stable version and opened bugreport with attached patch at debian ​https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=775029.

Thanks for your information!
