PythonHandler crash

[anonymous]

Since version 0.10.1 (0.10.2, 0.10.3rc1 - I'm not sure if 0.10 had this problem) sometimes the page is blank or it gives me Internal Server Error in browser. In apache logs I've found this:

I'm using Gentoo x86, apache 2.0.58, python 2.4.3, mod_python 3.1.4 and I have multiple tracs.
Before version 0.10 it never gave me that error.

Well, I guess that's because you also upgraded your SVN bindings and you use multiple virtual hosts.

See #2611, which is about the same problem and explains the reason and workaround, in the note in the ticket's description.
