Comment 18 Ray Strode [halfline] 2009-12-08 19:46:12 UTC
So the code has:

/* Used to count the number of clock instances. It's there to know when we•
 * should free resources that are shared. */•
static int clock_numbers = 0;•

[...]

⟾       clock_numbers++;•
⟾       e_passwords_init ();•


[...]

#ifdef HAVE_LIBECAL•
⟾       if (clock_numbers > 0) {•
⟾       ⟾       e_passwords_shutdown ();•
⟾       ⟾       clock_numbers--;•
⟾       }•
#endif•

The docs don't mention e_passwords_init being ref counted internally, so i don't know why we're calling init() and shutdown() more than once.

Looking at the code e-d-s code, there's a bug in shutdown:

def WITH_GNOME_KEYRING•
⟾       g_free (default_keyring);•
#endif•

default_keyring isn't getting nullified after the free.  This makes the shutdown function not idempotent.

Two possible fixes:

1) nullify default_keyring on free
2) only call shutdown when clock_numbers decrements to 0.

Given that clock_numbers is only used for shutdown and init, i'll assume it's original intent was for 2 to happen and someone just had a think-o.

I have updated to gnome-panel-2.28.0-16.fc12 from the page mentioned above. Sadly I am still not able to press ALT-F2 (i.e. open the run dialog).

I installed all debug packages and attached gdb to gnome-panel:

Hi Felix,

This bug was meant to address a crash in the clock applet, not the run dialog.  If you are one of the many duplicate bug reports on this bug, you may have been misduped.  Can you reopen your bug report?

Comment 22 Felix Möller 2009-12-09 21:10:42 UTC
I have been the first dupe of this report in comment #2 i reported my issue now at bug #546043.
