plasma-desktop crashes after update
I updated recently (after a few weeks). After a full update and reboot, after login I get a nice dialog saying plasma-desktop segfaulted. If I try to manually run the plasma-desktop binary, it says "Communication problem with 'plasma-desktop', it probably crashed"
Anyone else seen this or know what's going on?

Re: plasma-desktop crashes after update
In the journal, I see:
Sep 01 23:23:53 nathanb-box kernel: plasma-desktop[758]: segfault at 8 ip 00007fba0813db37 sp 00007ffdaf38f500 error 4 in libQtCore.so.4.8.7[7fba07f86000+2f8000]
Googling suggests that this can be a symptom of a variety of causes, though the most likely root cause would be plasma attempting to load something now incompatible with the new version...still investigating
Edit1: the old standby of removing .kde4 does not fix the problem.

Re: plasma-desktop crashes after update
KDE4 is not supported. Upgrading to the latest plasma 5 is the best solution, but you may have some success rebuilding your old packages against the new libraries.
Moving to AUR Issues.

Mobo: MSI MAG X570S TORPEDO MAX // Processor: AMD Ryzen 9 5950X @4.9GHz // GFX: AMD Radeon RX 5700 XT // RAM: 32GB (4x 8GB) Corsair DDR4 (@ 3000MHz) // Storage: 1x 3TB HDD, 6x 1TB SSD, 2x 120GB SSD, 1x 275GB M2 SSD
Making lemonade from lemons since 2015.

Re: plasma-desktop crashes after update
Yeah, I eventually came to the conclusion that somehow (probably due to unsplitting and renaming of certain key packages) my unsupported, dodgy KDE4 setup had finally reached the point where I couldn't maintain it from the official repositories anymore.
I gave plasma 5 a go back when support for KDE4 was dropped and I would honestly rather use Windows. I would call it many things, but "the best solution" is not among them.
I have worked around the issue by switching to Cinnamon for my desktop environment. We'll see how I get on. Long term solution will probably involve finding a well-maintained KDE4 AUR package, maintaining my own KDE4 install separate from the repositories (ugh), or switching to a distro that supports a larger selection of actually usable desktop environments.
Thanks for your response WorMzy.
