adding/editing layer feature crashes qgis master when OTF reprojection is enabled

[qgib]

Author Name: Mathieu Pellerin - nIRV (Mathieu Pellerin - nIRV)
Original Redmine Issue: 9049
Affected QGIS version: master
Redmine category:projection_support
Assignee: Marco Hugentobler

---

Steps to reproduce:

1. Create a new project
2. Activate OTF reprojection, make sure the CRS is WGS 84 (EPSG:4326)
3. Add a new vector polygon layer (memory layer will do just fine)
4. Activate editing toggle for that layer
5. Try to add a feature
6. Instant boom crash

The same is true if you try to edit features (i.e. move feature and/or one node). That can't be more than a two weeks old crasher as I remember doing feature edits / additions under qgis master not so long ago. Setting priority to blocker.

Hm, does not crash here. What CRS (and what datum transform) do you assign to the newly created layer?

Marco, here are my settings:

1. Project CRS: WGS84, OTF reprojection on
2. Newly created layer CRS: WGS84

I'm on a Linux machine, running latest master package (891fa7c) offered by the qgis.org ppa.

In the same environment as Mathieu I can replicate it all the time with the described steps (adding/editing a memory layer)

I tried exactly those steps and cannot replicate here (todays master). Any special options that need to be set?

Marco, are you running QGIS on windows or linux?

Hi Mathieu,
this can be a plugin issue after all. I disabled all plugin but the "new memory layer" one and the crash is gone.

Please test.

Giovanni, disabling all plugins doesn't bring me much luck over here, still crashing.

this is weird, now I cannot replicate the issue anymore.

The debian-nightly ppa had an update to its qgis master build with which I can't reproduce crash anymore. Looking into recent commits, I think Jurgen fixed this issue in commit 86b6c5b (https://issues.qgis.org/projects/quantum-gis/repository/revisions/86b6c5bbdfe75c293e2b0b86c9d1ce2f484b7a9e).

Closing.
