           Summary: Crash using shortcut for Add Method...
           Product: kdevelop
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel kdevelop org
        ReportedBy: hattons globalsymmetry com


Version:           3.0.90-CVS (using KDE 3.2.2, SuSE)
Compiler:          gcc version 3.3.1 (SuSE Linux)
OS:                Linux (i686) release 2.4.21-215-default

I set the shotcut for Class browser -> Add Method... to Alt+M.  When I hit Alt+M while the editor had focus, KDevelop crashed. I was able to reproduce that crash 3 times.

I then tried to use the shortcut with the focus in the Class browser.  That opened the Add Method dialog, but crashed when i submitted the dialog.  I was not able to reproduce that crash.

Adding a member function works if I open the Add Method dialog with a mouse click. 

Here is a backtrace of the crash with the focus in the editor:
