Crash when searching in Options #40111

rduivenvoorde · 2020-11-16T21:04:14Z

QGIS crashes (even with a fresh profiles path) when you search for something (in the search/filter box) in the main settings dialog.

To reproduce:
qgis --profiles-path /tmp/crash
open settings/options
first click somewhere in the left column with tabs, then start to type fast something in the search box
repeat a couple of times
if NOT crashing
create a second profile
and try again

I can easily reproduce it here with the latest build

Trying to reproduce in QtCreator here.
Crash seems to happen when you first search for something available (eg 'time') then select everything and start typing something else...
Other crash view:

gioman · 2020-11-16T22:07:26Z

after a few tries I was also bale to replicate on Windows: master, 3.16.0 but NOT on 3.10.11

lpinner · 2020-11-16T22:19:47Z

I was about to post the same/similar issue (QGIS 3.16.0 QT 5.12.8 Ubuntu 20.04). I found that QGIS only crashes for me when searching in settings if the core Processing plugin is enabled.

Seeing this on a fresh crash, now. Not sure if it is related.

@lpinner I can NOT confirm that it only crashes WITH processing enabled. Currently I get crashes when processing is enabled or not.

rduivenvoorde · 2020-11-23T09:20:24Z

I also have crashes in 3.16 freshly compiled.
Another (settings/options) related observation when compiling:

I can reliably crash master by searching for "highlight". It always crashes after the second i.

rduivenvoorde · 2020-12-02T06:05:59Z

Mmm, with me this started when I searched for 'time' .... 'i' related? The crash is also in he 'highlight' code if I am correct (the stuff that your search string is highlighted in yellow).

phidrho · 2020-12-02T14:12:42Z

Today it crashed twice for me on Win10, QGIS 3.16.1
I wanted to search for "select", and it crashed after entering "sele".

User Feedback

I was searching through Options with "select" keyword. Program crashed after entering "sele"
