core dump on loading project - fix broken PostGIS layer #19154

Closed qgib closed 5 years ago

Author Name: Gavin Fleming (@gubuntu) Original Redmine Issue: 10772 Affected QGIS version: master Redmine category:project_loading/saving

I opened a project that had a missing PostGIS layer. The dialog to fix the broken layer came up and immediately, QGIS crashed. 

Warning: Loading a file that was saved with an older version of qgis (saved in 2.3.0-Master, loaded in 2.5.0-Master). Problems may occur.
QGIS died on signal 11Could not attach to process.  If your uid matches the uid of the target
process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try
again as the root user.  For more details, see /etc/sysctl.d/10-ptrace.conf
ptrace: Operation not permitted.

So I ran QGIS as root, I could fix the layer without crashing. Thereafter the project opened fine running QGIS as my user again.

I see that you are using master, does this happen also on 2.4?

Is there a particular reason why you think that running as root would have changed something?

The main reason I can think of is a configuration issue. Can you try to move your .qgis2 folder to another location temporarily so you start with a clean configuration from scratch and then check if you still get a crash.

closing for the lack of feedback ("try again as the root user" is an unrelated message from gdb, when trying to attach to the qgis process after the crash fails)
