Sentry Crash Report:

Description Marcus Meissner 2014-04-29 13:48:19 UTC 
If the root password contains a " it is not understood by kdesud.

kdelibs/kdesu/client.cpp escapes it correctly

so    foobar"      turns into    "foobar\""
but the lexer.cpp in kdesud then chokes on that (returns Tok_none instead of Tok_string).


Reproducible: Always

Steps to Reproduce:
1. use rootpassword with " in it
2. try kdesu xterm 
3. fail
Actual Results:  
does not do anything

kdesud(22412) ConnectionHandler::doCommand: Parse error 

in .xession-errors

Expected Results:  
should open root xterm
