I have spotted another problem:
when you write something like $$ text $$ in a chatwindow and you are using the 
latex plugin text is sent to kopete_latexconvert.sh as an input parameter. 
Since this is a command line parameter characters like \f \t etc etc are 
interpreted as special character. It happens you have to write something like 
\frac which is of course misunderstood by the script. A solution would be 
escaping backslashes. 
In latex.ccp you should add in the handlelatex method (I think, I'm not a lot 
into Qt)

QRegExp backslash ( "\" );
latexformula.replace( backslash, "\\" ); 

Maybe other kind of characters should be escaped, like $.

Sorry, I can't provide any patch cause I haven't got kopete 0.12.3 source 
files. Hope some of the developpers can provide some kind of fix for this. 
Thank you
Andrea
