Created attachment 61099 [details] New crash information added by DrKonqi kontact (4.4.9) on KDE Platform 4.5.5 (KDE 4.5.5) using Qt 4.7.0 - What I was doing when the application crashed: I clicked on an IMAP folder and Kontact crashed. I have many IMAP folders. It does not happen always. I use Kwallet to store passwords just in case that is important. -- Backtrace (Reduced): #8 0x00007ff4bb71943b in __libc_message (do_abort=<value optimized out>, fmt=<value optimized out>) at ../sysdeps/unix/sysv/linux/libc_fatal.c:189 #9 0x00007ff4bb7234b6 in malloc_printerr (action=3, str=0x7ff4bb7f7098 "double free or corruption (!prev)", ptr=<value optimized out>) at malloc.c:6283 #10 0x00007ff4bb729c83 in __libc_free (mem=<value optimized out>) at malloc.c:3738 #11 0x00007ff4a18e42b7 in KMail::FolderViewItem::updateCounts (this=0x3214260) at ../../kmail/folderview.cpp:2850 #12 0x00007ff4a18e459d in KMail::FolderView::activateItemInternal (this=0x2cebfc0, fvi=0x3214260, keepSelection=false, notifyManager=false, middleButton=<value optimized out>) at ../../kmail/folderview.cpp:1023
> Opening a specific IMAP folder which contains about 90,000 messages Please revisit this issue with Kontact from kdepim 4.6.0
(In reply to comment #2) > Please revisit this issue with Kontact from kdepim 4.6.0 On Ubuntu 10.10 - KMail 1.13.6, KDE 4.6.2 - the situation has improved a bit. Kontact/KMail doesn't crash anymore on opening the problematic folder it doesn't show it's contents either, though, but rather a dialog that says: "Error while listing the contents of the folder Ubuntu-Users. The process for the imap://imap.example.com protocol died unexpectedly." The content of the dialog's "details" section isn't too helpful either, I guess: "Unexpected Program Termination The program on your computer which provides access to the imap://imap.example.com protocol has unexpectedly terminated. Details of the request: URL: (unknown) Date and time: Sunday 17 Jul 2011 10:51 Additional information: imap://imap.example.com Possible causes: [...] What can I do to get useful info about the problem?
> On Ubuntu 10.10 [...] Nonsense, it's Ubuntu 11.04. Sorry.
Doesn't change much, the current kontact / kdepim version is 4.6.1
I confused KDE SC with kdepim version-wise. It seems, ATM, the only easy way to get kdepim 4.6 is to install it on openSUSE. I'll create an openSUSE VM next week and report the results.
In kdepim 4.6, the problem seems to be solved. I couldn't reproduce the crash with kdepim 4.6.1 / KMail 2.1.1 / KDE 4.6.5 installed from the following repositories: http://download.opensuse.org/repositories/KDE:/Release:/46/openSUSE_11.4/ and http://download.opensuse.org/repositories/KDE:/Release:/46:/kdepim46/KDE_Release_46_openSUSE_11.4/
