From looking at the code I have surmised where the crash might be occuring and I have checked in a fix. It looks like a certain plugin is not registering its mimetypes correctly - the code did not previously handle this situation and a null pointer gets dereferenced. I have added some error checking to handle this. If someone can point me to the plugin that exhibited this problem, I can test the fix fully.

sorry, bad report.. the apprunner application was the problem.... I never managed to start it at all... if it is looking in any of my plugin directories(NN4) it will find the following dll's: npaudio npavi32 NPBeatnk NPBatSP npdsplay npjava32 npnul32 nppdf32 npPhoneFree nppl3260 Npqtw32 NN4.5: same as above and npswf32 and NPBeatSp with no exxtention. NN3 same as NN4 and ShockwavePlugin.class

Please try removing the npjava32.dll and see if it still crashes on start up.

Try the latest build. This crash no longer happens :-)

Apprunner component being deleted/retired at end of week. Moving all Apprunner bugs past and present to another appropriate component.
