[Qgis-user] Segmentation fault at start

[emmexx]

I'm using a qgis-master version in parallel with qgis 2.6 on linux 
slackware 14.1.

I used the qgis-master a few times with no problem. A few minutes ago I 
used it to load a wfs layer from a geoserver and edit a feature. I 
closed it and now I get a segmentation fault:

./qgis

Qgis 2.6 works as expected.
What should I check/delete/restore?

Thank you
