Chatty segfaults when trying to scroll chat details with many users

When trying to scroll down chat details with (at that time it had) 300+ users the chatty is crashed by Xerror

(sm.puri.Chatty:157980): Gdk-ERROR **: 11:07:53.618: The program 'sm.puri.Chatty' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 6695629 error_code 11 request_code 130 (MIT-SHM) minor_code 5)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
Trace/Breakpoint ausgelöst (Speicherabzug geschrieben)

Assuming above warning about async behaviour the backtrace is useless nevertheless will put it here for the reference (no idea how to approach this)
