With a particular project of mine (I don't know if it applies with other projects) when I click on the Documentation tab on the right, to open it (in IDEAL mode) kdevelop crashes with this stack trace:
[N.b. I've compiled everything without debug information... If you need I'll recompile kdevelop with debug on. Is it necessary to recompile kdelibs, too?]
(no debugging symbols found)...(no debugging symbols found)...
