That was me (both with the commit and suggestion in #pidgin). It
definitely fixes one version of the patch, but the original ticket
predates the addition of SSL support for OSCAR, so clearly there's
another issue going on there. (I'm staring at the code and just not
seeing how the crash is possible...)
I just committed bc9c4bb89eb6d36c548b61d8b1e6b8952b9c4c0e (trivial
printing out of pointer values), which will be helpful in correlating
where the timeout is coming from. Logs+backtrace from this crash with
that patch would be awesome!
