[QGIT PATCH/RFC]

[Abdelrazak Younes <younes@lyx.org>]

Hello Marco,

While recompiling latest qgit4, I stumbled accross this. I am not quite 
sure you used a QLatin1String instead of a QByteArray but the attached 
seems to work fine...

Anyway, I'll let you decide what do to with it.

Thanks for QGit,
Abdel.
