Comment 8 for bug 1980299

I think I may have found the source, but I'm not at all sure. I tether my Android phone to share the internet connection with my laptop. Each time I plug in the USB cable, a dialogue appears on screen with a message like this:

"Unable to mount Samsung Android
Unable to mount MTP device"003,027""

If I watch xrestop while this happens, the memory use for Metacity goes up by ~300KB each time. Given I only reboot when I get a new kernel (maybe once every 10 days or so), and generally leave my phone plugged in all day (complete with a dodgy plug!), it will show this message multiple times and thus slowly raise the memory used. Closing all the dialogue boxes reduces the xrestop memory value for metacity back to the value it was at before plugging in the phone repeatedly.
