I tried both actions at least 10 times on my two systems each and could not reproduce a crash. Do you have any other suggestions for reproducing it?

not really. but this is why we have stacktraces.

stacktraces can be used by the developers to figure out what went wrong.

stacktraces are used to find out the cause of those once in a million crashers.

Indeed it is. Thanks to the stacktrace, I can see where the pointer went null but have no idea how that code path could've been taken. It'd be kinda painful to check every foo->bar reference for nullness, or even what to do when that happens.

Maybe this should be forwarded upstream, since it's a development version and they'd be more interested about this crasher?

Judging from the stacktrace, it seems like you were toggling the fullsceen option which caused this.

Your Ubuntu version is EOL on the desktop. Can you reproduce this error with a supported Ubuntu version? Thank you!
