pantheon-mail crash when clicking one of my emails

gdb backtrace

(pantheon-mail:7989): Gtk-WARNING **: 11:45:01.430: Could not load a pixbuf from icon theme.
This may indicate that pixbuf loaders or the mime database could not be found.

(pantheon-mail:7989): Gdk-ERROR **: 11:45:01.487: The program 'pantheon-mail' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 39899 error_code 11 request_code 53 (core protocol) minor_code 0)
  (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.)

Thread 1 "pantheon-mail" received signal SIGTRAP, Trace/breakpoint trap.
