Application: konqueror (4.4.00 (KDE 4.4.0))
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.9-70.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
After upgrading to KDE 4.4, Konqueror is not willing to start any more, immediately crashing after either clicking on its icon, or trying to launch from the command line. In the latter case, the following is written onto the standard output (or standard error):

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
KCrash: Application 'konqueror' crashing...
sock_file=/home/chreex/.kde/socket-kurblivas/kdeinit4__0

I manually removed the sock_file mentioned. After that, the output changed as follows:

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc
KCrash: Application 'konqueror' crashing...
sock_file=/home/chreex/.kde/socket-kurblivas/kdeinit4__0
Warning: connect() failed: : No such file or directory
KCrash cannot reach kdeinit, launching directly.

drkonqi(19723) KCrashBackend::constructCrashedApplication: Executable is: "/usr/bin/konqueror"
drkonqi(19723) KCrashBackend::constructCrashedApplication: Executable exists: true

Other KDE applications start, except for KMix, which throws the same std::bad_alloc exception. I have read on some forum, that KDE 4.4 eventually does not work with already existing ~/.kde directory, so i renamed it to let KDE create a new one from scratch - but things did not change, so I reverted to my old .kde directory.

I am using Fedora 12 with the current latest packages. (I am not totally sure that this is the right place to report, but the Crash Reporting Assistant took me here.)

The crash can be reproduced every time.
