#17291: Fix crashes when some external APIs fail
 Reporter:  Zhouyang  |      Owner:  EionRobb
     Type:  defect    |     Status:  new
Milestone:            |  Component:  unclassified
  Version:  2.12.0    |   Keywords:  API bugs

 I'm a PhD student. I analyzed the pidgin source code and found some
 potential API bugs that may cause crashes.

 These crashes are mainly caused by insufficient error handling of API
 functions like fopen, g_dir_open, g_module_open, gethostbyname or socket.

 I think it's unsafe to assume the library function would be correct. It
 would be better if we could handle the error properly.

 Attached please find the patch against version 2.12.0. Hopefully, it can
 solve these potential bugs.
