           Summary: kate crashes on startup
           Product: kate
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: [email protected]
        ReportedBy: [email protected]


Version:            (using KDE Devel)
Installed from:    Compiled sources
Compiler:          gcc 2.95.3 (whole of KDE compiled using "ccache" -- everything else works fine)
OS:          Linux

I can't start kate without it crashing during startup. I've been running CVS since nearly a year now,
with weekly updates. My user "kdehead" has a complete CVS environment of its own. Last update was 
last night. 

kate has a problem on my box since ~ two months. The crashes occured initially only when launching 
kate from the kicker button, but it started fine from a konsole or xterm window.

Now it also crashes when starting from konsole. Here is what happens:

     kdehead@kde-bitshop:~> kate&
     [1] 30381
     kdehead@kde-bitshop:~> kio (KTrader): KServiceTypeProfile::offers( KTextEditor/Plugin, )

Then the kate crash handler dialog appears. The backtrace is this:

Please tell me if you can derive s.th. from this. What other tests can I run to track it down?
This is probably just s.th. wrong on my particular system. (I've upgraded the qt-copy 2 days ago), 
as this seems not to have occurred to anybody else.
 
Cheers,
Kurt
