Ok, i didn't know if that was the bug or not, so reading the bug i see two 
things you mention.

* The msgctxt has to match the source code context exactly and the comment has 
to be put before the entry as a plain comment.
	I do not agree with this, anywya seems more a stylistic thing than a real 
problem.


* When converting such PO file back to TS with lconvert, the context is lost.
	That doesn't happen here, i'm attaching my kcompletion5_qt.po and the ts 
genereated with lconvert. The ca.ts is fine, no?

Cheers,
