Original Redmine Issue: 15689
Affected QGIS version: 2.16.3
Redmine category:project_loading/saving

I often have this problem - when I open a project containing WMS layers, it crashes and I have to create it from scratch again.

in gdb:

Can you provide a backtrace from gdb? (Type 'bt')

Are you able to share your project?

The guilty project file is attached. The localhost layer won't work for you as it is an ssh tunnel.

Hmmm not much to go on there. Are you able to self build a debug version? I can't reproduce any crash with the project, but it's probably because of the missing WMS layer

Hi Gavin

Few questions :-)

  • can you confirm the problem persists if you disable all plugins?

  • can you confirm the problem persists in 2.18? there were some updates that may have helped

  • does it matter from what kind of source the WMS layer is coming from (e.g. it only happens with your "local" server, but not "remote" servers)?

  • does the project need at least two WMS layers in order to crash?

  • how often would it crash? Once in ten times you open the project?

Nyall I'm not sure when I'll be able to get around to building a debug version.

Martin

It just opened for me but I hadn't opened the ssh tunnel so it complained about a missing layer. So I then opened the tunnel and came back and said OK..then it proceeded to load both layers. It seems like the first one had time to load in the meantime? When I re-opened the project with the tunnel already open, it crashed again.

  • I can confirm it still crashes with all Python plugins disabled (after restart)
  • I haven't built 2.18 yet
  • not sure
  • haven't tested thoroughly yet
  • in this case every time (except in the fortuitous instance described above)

I have a similar problem that started with 2.18. My platform:
Ubuntu 16.04 64bit, QGIS 2.18.0 from ubuntugis

I cannot add WMS layers to a project if I enter a tilesize (for example 256 x 256) in the WMS dialog. QGIS crashes immediately after pressing "Add" in the WMS dialog.

When opening old projects (from 2.16.3) with such tiled WMS-layers in 2.18.0 QGIS crashes as well. It worked fine with QIGS 2.16.3 from ubuntugis.

The same problem apears in QGIS 2.18.0 for Windows 64Bit installed with the osgeo4w installer.
QGIS crashes when I try to add a WMS layer with a tile size. The same layer without a tile size will work correctly. The WMS Server is a Geoserver 2.10.0. There where no problem with QGIS 2.16.3.

Christian / Marcus: your problem involving crash with tiled WMS in 2.18 has been reported in #23719 and fixed (was introduced within 2.18 development). The issue Gavin reported is a different problem as it has been reported for 2.16

I played a while with the attached project, adding other wms layers, reprojecting, etc. No crashes on 2.18.4 on Ubuntu 16.04

I assume the issue could have been fixed. Please reopen if is not.

  • resolution was changed from to not reproducable
  • status_id was changed from Open to Closed
