The following happens when I try to save edits to PostGIS layer. Tested both on localhost and remote server. Postgis 2.1.7 running on PostgreSQL 9.4.

Fatal: ASSERT failure in QList<T>::operator[]: "index out of range", file /usr/include/qt4/QtCore/qlist.h, line 477

Hi Michal,

Can you add some information about the table in question and the type of edits that you have made?
In particular, have you been adding or removing columns in the QGIS session?

Hi Matthias,
I would love to but I switched to master when this error ocurred. It seems to be fixed in master.
