Could you please avoid inserting formatting in plain text? Obviously those 
asterisks below aren't part of the source code.

Your error was to use startDetached. That's a static function. Unlike Java, 
C++ does let you use the context of an object to call a static function. But 
to be on the safe side, you should have written:

	QProcess::startDetached(svnprogram, arguments, workingdirpath);

if you had done that, you'd have noticed that you never started a process in 
proc1. That means startDetached is the wrong function to use. You simply 
wanted start().
