While I have never had this problem, this is the correct place to open the issue. Please fill out the rest of the template though, as otherwise many here won't work on it. In particular you should also open a downstream bug report with LinuxMint (which I'm pretty sure builds their own MATE packages rather than using Ubuntu's or at least they used to). I suspect this may be another distro-specific bug, thus the need for a downstream issue to go with this

I've never once had this happen except when hacking on experimental code on the applet and even then not on mouseover. Also useful would be the backtrace generated by gdb, run
thread apply all bt full
to get it

I am an intermediate level user-- not advanced. I have no idea what the other stuff is, or where to look it up.

Not much more I can do myself as I cannot duplicate the issue. I am on Debian, now with mate 1.23 but never had this happen on 1.20 when I was using it some time back.

https://bugs.launchpad.net/linuxmint has not been configured, I don;t know where LinuxMint takes bug reports as a result, but Ubuntu takes theirs at https://bugs.launchpad.net/ubuntu and Mint's forums are at https://forums.linuxmint.com/

@clefebvre this is something you should take a look at as you work on Mint and this is rather serious, it blocks using the volume control

I can confirm the issue on Manjaro with MATE version 1.26.0 with mate-media version 1.26.0-1
Sometimes (maybe once or twice a day or every other day) when you hover over mate-volume-control-status-icon) it will crash with the following output (I presuming the output is sent to stderr):

(mate-volume-control-status-icon:116748): Gtk-WARNING **: 19:30:43.174: Calling gtk_widget_realize() on a widget that isn't inside a toplevel window is not going to work very well. Widgets must be inside a toplevel container before realizing them.
