Subject: GNUS crashing too often (emacs-24.1-1958-g9d4216a)
Date: Mon, 23 Jul 2012 21:10:04 +0300

Hi.

I got latest emacs from git today (emacs-24.1-1958-g9d4216a).

When I work in GNUS, it's crashing too often (and randomly).
Here is GDB stack trace... NULL pointer is seems coming into
string_count_byte8()

Any other info I can get? elisp backtrace?

Program received signal SIGSEGV, Segmentation fault.
