crash on double clicking a file

Sat Feb 23 16:29:02 UTC 2002

Hi,

Attached is a core dump of kdevelop from KDEVELOP_2_BRANCH.
It crashed after double clicking a file from the file viewer.
Commenting out lines 3978-3980 from ckdevelop.cpp seems to solve
it but I don't know if thats the right solution:

//    if(project && build_menu->isItemEnabled(ID_BUILD_MAKE)){
//      enableCommand(ID_BUILD_COMPILE_FILE);
//    }

I can't see where build_menu is allocated in the code.
