Bug 74680

Hmm.. I doubt this is an "important" crash (but it should or course be fixed) it probably comes about because KDevelop is in an "undefined state". The reported error should be considered a terminal failure when a C++ project is loaded, it's an install issue, not a settings issue.

The failure to find the find the C++ language plugin has come up before in the mailinglists. IIRC Berkeley DB is commonly involved (again). Try running KDevelop from a terminal and see if you get any debug output when the error occurs. A relocation error in particular is something to watch for.

IMHO you simply forgot to run kbuildsycoca. At least that was the message I used to get when I forgot about it :)

I wish that was the case.  This is all I get when running from shell : 

[user1@localhost usr]# kdevelop

I am actively watching my thread on the KDev forums for information, non of which at this point have solved the problem.  

Please run "ldd -r </path/to/>libkdevcppsupport.so" and see if this reports any undefined symbols.

I got the following for the above command :

Hmm.. nothing apparently missing there. No idea.

For some reason, libdb was listed there, but re-installing it (rpm -ivh) solved the ONE problem.  I can now start projects, but occassionally still get a SIG when I am entering the config dialog.  If I get any new debug information it will be posted here.  (I am marking this as solved, due to the one problem being fixed. )

Thank you.
