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

Gpaste-daemon 3.18.3-1 sometimes uses 99% CPU for a long time, maybe new 3.18.4 release fixes this issue?

[Amr Ibrahim (amribrahim1987)]

It could be "fix hanging issue due to gtk+ race (?) in gtk_clipboard_store"!

[Jeremy Bícha (jbicha)]

Amir, are you willing to commit to verify this fix for 16.04 LTS if someone uploads the update?

[Amr Ibrahim (amribrahim1987)]

Thanks Jeremy for following up.

Yes, I'm now on 16.04 w/ Unity and willing to verify the fix.

Note: GPaste 3.18 supports building a unity appindicator. Apparently, the Debian package did not build it. According to upstream: "If you also want to build the unity application indicator, you'll have to pass --enable-unity to configure." https://github.com/Keruspe/GPaste/tree/gpaste-3.18

My question is, could the unity appindicator be built with the proposed 3.18.6 update?

[Jeremy Bícha (jbicha)]

Amr, thanks. If this is accepted as an update, please test it on GNOME Shell too.

I don't intend to enable the appindicator because that feature was removed in gpaste 3.24.

[Jeremy Bícha (jbicha)]

Amr, I have uploaded this update to the unapproved queue for xenial. It will need to be approved by a member of the ubuntu-sru team before it is built and available for testing.

[Mantas Kriaučiūnas (mantas)]

Jeremy, I also wanna verify this fix for 16.04 LTS, could you upload gpaste 3.18.6 to some PPA, because now I can't find gpaste 3.18.6 ppa packages :(

[Amr Ibrahim (amribrahim1987)]

3.18.6 is now in the Unapproved queue https://launchpad.net/ubuntu/xenial/+queue

[Jeremy Bícha (jbicha)]

Mantas, see comment #6 above.

Personally, I usually prefer to wait a bit longer for the Stable Release Update team to approve the update so that the fix is available for all Ubuntu users rather than just those who find and install from a PPA.

I apologize for the inconvenience, bu this bug has existed for a year so maybe a couple more weeks is ok?

I tested 3.18.6 from xenial-proposed. It's working well.
