[SOLVED] Regression in okular 26.08.0-1 causes kile to segfault

The okular update to 26.08.0-1 seems to create problems in other kde software relying on okularparts. Kile is one example. Starting kile results in an immediate segfault which happens when kile tries to create an Okular::Part instance (check out the crash dump below). Rolling okular back to 26.04.3 fixes it. Did anyone run into this problem? Is this a packaging error or a bug in KDE Gear?

Application: Kile (kile), signal: Segmentation fault

Re: [SOLVED] Regression in okular 26.08.0-1 causes kile to segfault

Nice. I see the package is already updated and the update fixes the segfault.
