Hi :)
That sounds like a bug to me
http://wiki.documentfoundation.org/BugReport
On Ubuntu the LibreOffice 3.3.2 has no trouble.  Can you try the 3.3.3 to see if 
you have the same trouble?

Subject: [libreoffice-users] Re: Displaying Negative Numbers as red in Calc
I have an iMac, System 10.6.8 and Libre 3.4.1
In Calc I have no problems with red negatives, two decimal places and comma
separated thousands when saved as odf
However, when saved as xls, the red negatives are all black, but the
thousand separator and the two decimals are OK. 
In xml, fods, format, everything works OK.
Tink.
