Looks like another variation on #397817, although it's not a scenario described exactly in that other BR.

Comment 2 Stephan Kulow 2023-02-28 16:47:43 UTC

If the crash can be reproduced, please let us know if a) it also happens with an updated version and b) if the drkonqi reports are the same or different.

Comment 4 Brian Kaye 2023-03-15 17:20:24 UTC

kpat killed by SIGSEGV.  The program now quits switching between golf and patience. Some time it just quits and sometime it quits with a chance of reporting or restarting

Comment 5 Stephan Kulow 2023-03-17 16:48:21 UTC

But that is still kpat 20.12 on Fedora 34?

Comment 6 Brian Kaye 2023-03-18 02:21:05 UTC

Mine is version 22.12.3 on fedora 37. The failure for me now is only switching after a successful win on golf to a new game on klondike.  It does not seem to eever fail with another game sequence. Sometime it doesn't fail which I suspect will make finding a solution difficult.

Comment 7 Stephan Kulow 2023-03-18 15:37:20 UTC

ok, the problem is that fedora didn't enable the blackhole solver for golf but the developers used version with it, so the alternative solver bitrotted. I removed it in master (so you wouldn't have any solver unless fedora enables it). I'm confident that the bug is there, but I'll try to win golf for a bit.

Comment 8 Stephan Kulow 2023-03-18 15:50:40 UTC

Created attachment 157389 [details]
golf save game

But I compiled an old version without BH and still can't reproduce. For that I load the attached game, move the three final cards and after the animation press "New Game" on the toolbar and pick klondike.

Comment 9 Brian Kaye 2023-03-18 22:58:09 UTC

Tried the attached game several times. No  crash  or quit after selecting klondik any of those times.

Comment 10 Brian Kaye 2025-06-29 19:47:10 UTC

No problem in latest versions
