GIMP consistently crashes when using drawing tablet

[Justin Tracey]

Xubuntu 23.10
GIMP 2.10.34-1

I can sometimes get a couple brush strokes in, but consistently, the program crashes quickly once I start using the drawing tablet. I thought maybe it had something to do with multi-monitor setup, but it happens when only using one monitor as well. XFCE so X, not Wayland. Tablet model is reported by xsetwacom as "Wacom Bamboo 2FG 6x8". This did not happen in Xubuntu 23.04.

[Michael Schumacher (schumaml)]

This is https://gitlab.gnome.org/GNOME/gimp/-/issues/9385 - triggered by a change in linuxwacom, fixed in GIMP 2.10.36.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Łukasz Zemczak (sil2100)]

This sadly affects me as well, confirmed that GIMP 2.10.36 from noble works fine. I backported the noble version to mantic in my PPA ppa:sil2100/gimp as a temporary workaround to get this working back again, but I think someone should fix this properly and upload to the -updates pocket as an SRU.

Just to be clear: for me GIMP from 23.10 is 100% unusable with my wacom tablet. Even one touch on the canvas causes the outlined crash. With 2.10.36 the crash is no more.
