Problem : with fluidlauncher demo : QFontEngineQPF failed

[post4pavan]

Hi all,

I have launched Qt_Demo fluidlauncher with qws.
@./fluidlauncher -qws@ is what I have used.

The error I get is
@Initializing QFontEngineQPF failed for /usr/local/Trolltech/Qt-target-version/lib/fonts/DejaVuSans.ttf
Initializing QFontEngineQPF failed for /usr/local/Trolltech/Qt-target-version/lib/fonts/DejaVuSans-Bold.ttf@

I am of no clue regarding this error, as even Googling got me confused.
Please Suggest!
