           Summary: KMail sometimes crashes X when opening the composer
           Product: kmail
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: unspecified
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: ralfjung-e at gmx.de


Version:           KMail 1.12.4 (using KDE 4.3.5)
Installed from:    Ubuntu Packages

Sometimes when I open the messages composer (either by selecting "New message"
or by hitting "reply" in an existing message), the whole X server is crashing.
I am usually writing 5 to 15 mails each day, and this happens every 1 to 2
weeks - but when it happens, it's of course really annoying as *all*
applications are terminated.



The .xsession-errors file contains some messages like this:

kdeinit4: Fatal IO error: client killed
kdeinit4: sending SIGHUP to children.

but since there is no timestamp, it's hard to tell when they occurred.



The Xserver log file contains this backtrace:

Backtrace:
0: /usr/bin/X(xorg_backtrace+0x3b) [0x8133d6b]
1: /usr/bin/X(xf86SigHandler+0x55) [0x80c7d35]
2: [0x739400]
3: /usr/bin/X(FindGlyphByHash+0x3c) [0x816e71c]
4: /usr/bin/X [0x817b13c]
5: /usr/bin/X [0x81742e5]
6: /usr/bin/X(Dispatch+0x35f) [0x808d17f]
7: /usr/bin/X(main+0x395) [0x8072515]
8: /lib/tls/i686/cmov/libc.so.6(__libc_start_main+0xe6) [0x22cb56]
9: /usr/bin/X [0x80719c1]
Saw signal 11.  Server aborting.

Which is always the same except for the hex numbers in line 2 and 8. This
backtrace is of course rather useless without debug symbols, but I don't know
how to install them and get a good backtrace without having to compile X
myself.



I am using Kubuntu 9.10 and X.Org X Server 1.6.4. KMail is the only application
which ever triggered an Xserver crash so far.
