lxqt-panel 0.17.1 is leaking memory, v1.0.0 fixed it

[Tong Sun]

The culprit might as well be the same as reported in
https://bugs.launchpad.net/ubuntu/+source/lxqt-panel/+bug/1881397

The reason I'm opening this, according to upstream, where I initially reported the problem,
https://github.com/lxqt/lxqt/issues/2154
is that the problem has been fixed in the newest version.

So upgrading lxqt-panel from 0.17.1 to 1.0.0 should be able to fix the issue.

Please upgrade lxqt-panel to 1.0.0.

Duplicating my initially reported problem (at https://github.com/lxqt/lxqt/issues/2154) below:

It is surely leaking memory, otherwise, the heap won't be this big, 1.2G!!

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 1954844

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.

FYI: LXQt 1.0.0 has requirements that aren't available in impish/21.10, and it'll be available when you upgrade to 22.04/jammy in the future as mentioned at https://discourse.lubuntu.me/t/lxqt-1-0-0-released/2843/3

apport-collect reports much much more than I'm willing to share, and I believe what I've provided is sufficient.

So I'll pass this time.
