That's what you did, but the key question is: Is it enough to reproduce the crash _always_? I assume it crashed just once (because folder tree rebuilding works here with two different IMAP servers).
[...]
| #0 0x0822d185 in imap_threaded_select (folder=0x8908e70,
| mb=0x873e2b0 "INBOX", exists=0xbfb278a8, recent=0xbfb278a4,
| unseen=0xbfb278a0, uid_validity=0xbfb2789c,
| can_create_flags=0xbfb27898,
| ok_flags=0x89761e8) at imap-thread.c:1420
imap-thread.c is Claws Mail's src/etpan/imap-thread.c where it does:
| imap = get_imap(folder);
...
| if (!imap || imap->imap_selection_info == NULL)
| return MAILIMAP_ERROR_PARSE;
|
| * exists = imap->imap_selection_info->sel_exists;
The last line is 1420. So, it performs a NULL check for the "imap" pointer and the imap_selection_info pointer. That one is maintained by libetpan. Both must be none-NULL, or else it would have returned earlier. Then in line 1420, "exists" is a pointer to gint, so it would copy an integer. The pointer is created earlier in the backtrace as address of a gint on local stack.
It may make sense to look at recent changes in libetpan cvs.
This message is a notice that Fedora 14 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 14. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '14' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 14 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping |
