kdepim crashes during exit with QWidget error

Description

When I try any operation with the kdepim pluging, it crashes during exit (forcing a slow sync next time). The error is during the call to KABC::AddressBook::save from KContactDataSource::disconnect (see backtrace below). An error is reported from QWidget:

QWidget: Cannot create a QWidget when no GUI is being used

Here is the backtrace:

Program received signal SIGSEGV, Segmentation fault. 0xb6c9ae49 in QWidget::create () from /usr/lib/libqt-mt.so.3 (gdb) bt #0 0xb6c9ae49 in QWidget::create () from /usr/lib/libqt-mt.so.3 #1 0xb6d72eb9 in QWidget::QWidget () from /usr/lib/libqt-mt.so.3 #2 0xb76774ea in KIO::NetAccess::enter_loop () from /usr/lib/libkio.so.4 #3 0xb76b3c09 in KIO::NetAccess::synchronousRunInternal () from /usr/lib/libkio.so.4 #4 0xb76f21f1 in KIO::NetAccess::synchronousRun () from /usr/lib/libkio.so.4 #5 0xb644b288 in KABC::ResourceFile::save () from /usr/lib/libkabc_file.so.1 #6 0xb7a23256 in KABC::AddressBook::save () from /usr/lib/libkabc.so.1 #7 0xb7b95770 in KContactDataSource::disconnect (this=0x8086498, ctx=0xb374b6d0) at src/kaddrbook.cpp:87 #8 0xb7b90869 in KdePluginImplementation::disconnect (this=0x806da30, ctx=0xb374b6d0) at src/kdepim_impl.cpp:163 #9 0xb7f9aa16 in kde_disconnect (ctx=0xb374b6d0) at src/kdepim_sync.cpp:94 #10 0xb7efc047 in osync_member_disconnect (member=0x8071550, function=0xb7eddf30 <message_callback>, user_data=0xb375b940)

This crash is completely reproducible in my configuration -- every use of kdepim crashes this way during exit.

I can confirm that pmarat's fix fixes the problem for me as well. Can we get this included in the SVN version of kdepim?

06/03/06 12:03:25 changed by Graham Cobb

  • owner changed from abauer to ehabkost.
  • priority changed from normal to high.
  • component changed from OpenSync to Kdepim-Plugin.

06/03/06 12:11:43 changed by pmarat

I have allready included the patch in my svn debian packages.

This patch should not interfere with kitchensync-opensync.

  • status changed from new to closed.
  • resolution set to fixed.

Fix included on svn, commit [1035]. Thanks!
