When there's a lot of video control activity (pause/play/seek/etc) I'm seeing frequent SIGABRTs.  They seem to come in 3 flavors.  The first two are the most frequent (about 40 times over the past few days) and always seem to be relates to thumbnails.  The last one has happened only 3 times over the same period. 

I'm going to turn off thumbnails a bit and see if that quiets things down.

Fedora 35 XFCE and I do all my video control through MCWS.   I keep forgetting to turn logging on but I'll grab a log of the next occurrence.

FYI... Since turning off thumbnail generation and removing the thumbnail column from my views I haven't experienced any crashes.

FYI... Since turning off thumbnail generation and removing the thumbnail column from my views I haven't experienced any crashes.

Sounds like that might be a corrupt cover art image.

[RemyJ]

These are all thumbnails generated by MC <29  from mp4s. 
Maybe I need to clean them all out and let MC29 recreate them.

[RemyJ]

Just a followup...   Since about 29.0.26, I've not had a single crash but thumbnails are disabled and any existing ones have been cleaned out.  I'm going to turn them back on and see what happens.
