DrKonqi report (Aug. 4th 2018)

Reopening this bug to let everyone know it's NOT solved. Despite of its previous status ("RESOLVED DUPLICATE of bug 346118" - I highly doubt it's a duplicate).

Comment 4 David Edmundson 2018-08-04 22:08:01 UTC

Your backtrace clearly starts with:

Application: plasmashell (5.5.5)

and then I spent time reading further to see the line it refers to 566 is definitely changed and it isn't calling QAIM::dataChanged.

Maybe this isn't fixed, but that backtrace only shows that old versions before the supposed fix unsurprisngly don't have the supposed fix.

Comment 5 Valdo 2018-08-04 22:41:00 UTC

Thanks for your prompt reply David.
It's too technical for me (I didn't get that part: "the line it refers to 566 is definitely changed and it isn't calling QAIM::dataChanged.") but never mind, at least I prefer a CLOSED status than a RESOLVED one, since I'm facing that bug every day :)
So assuming Plasma 5.5.5 stopped being maintained a long time ago (funny for a Kubuntu LTS release btw), no chance there will ever be a fix, right?

Comment 6 David Edmundson 2018-08-04 22:47:26 UTC

From a KDE POV, we don't control what Kubuntu put in their LTS.
Our first LTS was Plasma 5.8.

There is the option of asking Kubuntu to backport the supposed fix.

Comment 7 Valdo 2018-08-04 23:22:40 UTC

I know KDE and Kubuntu teams are separate ones. Now, if Plasma 5.8 was the very first LTS, I understand there was no better solution at the time for the Kubuntu team than Plasma 5.5 (thanks for the explanation).
Getting in touch with the Kubuntu team could be an option, but considering the support of Kubuntu 16.04 will end in April 2019 (9 months from now), I guess the wisest option will be to upgrade to Kubuntu 18.04 when possible :) Better concentrate on 18.04 bugs than backport an uncertain fix for a very short duration...
