[Ubuntu] qgis-providers fails to install

[Jorge Gustavo Rocha]

Hi Martin,

It seems to happens when some QGIS tool runs.
My wild guess is to check if you are not running QGIS against some old 
PROJ or GDAL version. Check if you have some dangling PROJ or GDAL libs 
around.

I hope it helps. Good luck,

Jorge
