Crash to desktop on loading a decompiled Quake 2 map.

[eGax]

System Information

A Linux TrenchBroom build of the current master branch. v2021.1-410-gc038098fa Release Linux

Expected Behavior

Not crash when having issues loading a map, but maybe throw an error window and go back to the Welcome window so the user can select another map.

Steps to Reproduce

Download this quake 2 inland3_decompiled.map.txt, remove the .txt, open into TrenchBroom on Linux as a quake 2 map(shouldn't matter if you don't have Q2 setup or not), and TB will crash to the desktop with no obvious errors or warnings but does still write the trenchbroom-crash.txt to the documents folder.

Crash Info

Reason: /trenchbroom-git/src/trenchbroom/common/src/Model/Polyhedron_Clip.h:189: Condition 'initialEdge != nullptr' failed: initialEdge is null

trenchbroom-crash.txt

I do understand decompiled maps are problematic, but still, it would be good if TB was robust enough to handle errors without crashing. Just to note the same map loads into Netradiant-custom with no issues.

Thank you very much!
