New description:
I have created a default prefs.xml file by removing it from ~/.purple (as
suggested on https://developer.pidgin.im/wiki/TipsForBugReports) and then
running pidgin. Under various configurations of the boolean parameters the
system seg faults. I enclose the backtraces and the versions of prefs.xml
that cause these seg faults.
