Well Benoît,
Kendek already offered to patch the gb.cairo bug fix into his 3.4.2 PPA
(the one I am using). And since I already updated my Gambas version with
his patched one all is working just fine.

The application I need the fix for is one at work. Iḿ using PPA Kendek
there as well on all systems, so I should be fine.

But I will give your suggestion a try on a VM where I have a non updated
3.4.2 from PPA Kendek. Just out of curiosity

Thanks,
