[QGIS-Developer] Breaking default profile

Fri Jul 24 07:45:12 PDT 2020

Hi Devs,

I've had this week 2 times that my profile 'breaks', as in: QGIS (all versions I have master, 314 and 310) crash, I think during startup of the default profile.

The first time the profile was very old and had A LOT of plugins in it.
But the one of this week was rather small with just 3 small plugins.

Starting up another profile then is fine.
Normally I do a lot of switching between profiles, versions and language (switching using "--lang nl" because of my work for a dutch client). But not this week.

I was wondering if other encountered this? If not, forget about it :-)
But if others also have seen this, I think it is good to investigate further.

Regards,
Richard Duivenvoorde

I just started QGIS in gdb and then get the following BT,
