 Hi there -- I'm using Ubuntu Hardy and their backport repo just added
 version 2.5.0 of Pidgin. I found some other crash reports, most notably
 #3180, but it doesn't seem to be my crashbug, as mine occurs in what looks
 like SSL certificate handling.

 I get a SIGSEV, with the following backtrace:
 {{{

 Here's the pidgin output with "-n -d" and trying to activate an account
 which hits a local IRC proxy:
