Problem with git plugin

Hi,


I recently found that my kdevelop build doesn't show a context menu for the 
project view any more.  On debugging, I find that the git plugin tries to 
decide if it's going to provide a context menu extension, which causes a job 
to be executed and a new event loop created, so the execution seems to 
disappear into queryPluginsForContextMenuExtensions and never return.


Could this bug be only affecting me because I don't have git installed?  If 
so, can the bug be fixed please...


(please ignore the line number in projecttreeview.cpp, it's wrong, i added 
debugging calls)
