lxqt-panel leaks memory after running update-desktop-database

[Martin Thornton]

Ubuntu 20.04 LTS

lxqt-panel: 0.14.1-1ubuntu3

Every time update-desktop-database is run, for example after package updates, lxqt-panel leaks about 10MB of memory. Can leak as much as 1/2GB with long uptimes.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Please execute the following command only once, as it will automatically gather debugging information, in a terminal:

apport-collect 1881397

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.

Can you also provide some details about how you measured the 'leak', and what qualifies as 'long uptimes'.

Details about your install (clean install? upgraded from or history of system etc) would also be useful, though these will be obtained on running the requested apport-collect. Thanks.

Last uptime was from shortly after upgrading to 2020.04, so about a month.

I was able to reproduce the same high memory usage rapidly by repeatedly running `update-desktop-database` or by reinstalling user desktop files with `xdg-desktop-menu install`.

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

Is this still an issue with 22.04 or later?

No, there's no leak now using 23.10.

Assumed fixed then!
