QGIS crash when opening a layout

Category:Map Composer/Printing
Affected QGIS version:3.0.1 Regression?:Yes
Operating System: Easy fix?:No
Pull Request or Patch supplied:No Resolution:duplicate
Crashes QGIS or corrupts data:Yes Copied to github as #:26653



I've started to use QGIS 3.0.1 since last week. I've created the project with QGIS 2.18. There are about 50 layers, and 1 complex composer (an atlas of 7 pages, with several data tables and maps).
When opening the composer with QGIS 3.0.1, all data tables were deleted. I created them again without problem.
But since 2 days, QGIS crashes as soon as I try to display the composer.

Here is the report :

Can you please attach the crashing project with some (minimal) test data?

I'm sorry, but it seems that the 2 problems are quit different, no?

However I'd tried to unselect "Discourage labels from covering features", and then fully unable labels on all the layers of the project, but the problem still occurs.


I don't know how send some test data : some data are in a postgre database, and there are many shp files. I'd tried "GPackage" extension, but it doesn't modify the project (path and provider mainly). I can send qgs file alone, and/or pdf file exported by the composer from QGIS 2.18, if it can

Thank you.

It's the same underlying cause - an instability in the geos library on windows. When one is fixed the other will also be fixed.

Ok, thank you for your answer.
I don't really understand, because it was working without problem and all of a sudden I couldn't open my layout. I don't know why, and I don't know what to do to get back...

Have a nice day!
