Status changed to 'Confirmed' because the bug affects multiple users.

[Ryan Freitag (ryanfreitag)]

Got a new message notification after pidgin had been idle for 8 hours

[Paul Graydon (twirrim)]

Got this under 12.04 as well. Pidgin 1:2.10.1-1ubuntu2

[Max Liebkies (mliebkies)]

I am also having this bug with Pidgin 2.10.6 (libpurple 2.10.6). gdb gives me the following:

Program received signal SIGSEGV, Segmentation fault.
