 While trying to modify bug #137, I got the following error. Second try
 worked fine.
 Looks like trac should wait for the lock (up to a timeout of course) and
 try again instead of bailing out.

 ==== How to Reproduce ====

 While doing a POST operation on `/ticket/137`, Trac issued an internal
 error.

 the full version for the path instead of major.minor only. This works on
 Fedora and Ubuntu, but breaks on Debian. Any chance we could support both
 schemes?\r\nI currently need to follow xulrunner closely to ensure
 security updates are applied in sugar-jhbuild. For CVE-2009-1169 and
 CVE-2009-1044 I even need to pull distro patches since there's still no
 new upstream release containing the fixes (1 week and counting).\r\n\r\n",
