           Summary: Crashs while loading plugins after unloading plugins
           Product: kdevelop
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdevelop-devel at kdevelop.org
        ReportedBy: mail at sacu.de


Version:            (using KDE Devel)
Installed from:    Compiled sources
OS:          Linux

Yet another crash in kdevelop:

to reproduce:
a)
  - unload all global plugins
  - unload all project plugins
  - load all project plugins

or b) according to Jens Dagerbo shorter way to the same(?) crash:
  - unload globals
  - load a project (that has all plugins enabled)
