Bug report #15961

Escaping out of Dialog causes QGIS to crash

Added by ramon . over 7 years ago. Updated almost 7 years ago.

Status:	Closed
Priority:	High
Assignee:	Matthias Kuhn
Category:	GUI
Affected QGIS version:	2.18.7	Regression?:	Yes
Operating System:		Easy fix?:	No
Pull Request or Patch supplied:	No	Resolution:	fixed/implemented
Crashes QGIS or corrupts data:	Yes	Copied to github as #:	23877

Description

Pressing Esc in at least one dialog can cause QGIS to crash.

The known case can be replicated as follows:

I have a layer (shape in this case) with the properties open. I double click on the Symbol to get the Symbol Selector. Then I want to get out of the dialog and reach for Esc to close it. Nothing happens so I press Esc again and QGIS as well as the dialog closes up.

This is on Jessie, with 2.18.1.

There may be others, and if so, could they be added to this bug report.

Subject changed from Escaping out of QGIS to Escaping out of Dialog causes QGIS to crash

#4 Updated by Pedro Venâncio over 7 years ago

I can confirm this also in Windows. To replicate:

1) Add a shapefile / PostGIS layer;
2) Select the layer in TOC --> Layer Properties;
3) Style --> Categorized;
4) Column --> (choose one) --> Classify;
5) Double click on one Class symbol;
6) Click 'Esc/Escape' to close Symbol Selector window --->>> I get a crash here.
If I use 'Ok' or 'close' button, instead of 'Esc', then no problem.

This happens on QGIS 2.18.2 and master, but not on QGIS 2.14.10 (all from OSGeo4W 64bits), so it seems like a regression.
