Comment 1 Salvatore De Paolis 2010-07-21 11:03:44 UTC 
the stack frame goes into the Extended search instead of the From/To/Subject/Tag.
Did you someone switch to Extended search?
Also is this reproducible? I can't here.
If you can reproduce please, give the steps here.
Comment 2 Salvatore De Paolis 2010-07-21 11:10:38 UTC 
Err.. actually the CVS code is changed in such part. So it's right. Can you test the CVS code? I guess the bug may be already fixed.

hi, after two days the cvs18-build froze as well. There was no output on the console, while the backtrace looked similar:

Comment 4 Salvatore De Paolis 2010-07-24 07:46:22 UTC 
Created attachment 874 [details]
maybe fix invalid free of mem

Can you try the attached patch against CVS source?
Comment 5 Colin Leroy 2010-07-24 18:50:50 UTC 
g_list_free() of the last g_list_remove()d item is a bad idea !
Comment 6 Michael Rasmussen 2010-07-24 19:25:59 UTC 
Shouldn't the above be reversed?

Is:
if (last->data)
    g_free(last->data);
list = g_list_remove(list, last->data);

Should:
if (last->data) {
    list = g_list_remove(list, last->data);
    g_free(last->data);
}
Comment 7 Colin Leroy 2010-07-25 09:33:24 UTC 
Indeed, it should. Commited :)
