Package: libkf5kiocore5
Version: 5.54.1-1
Severity: normal
Tags: patch upstream


Dear Maintainer,
in the last year I hit a few crashes with kate,
without knowing how to reproduce the crash.

Today I found this upstream reports [1] and several
duplicates. With that information it was easy to reproduce
the crash by just creating several nested folders in the
save as dialog of okteta.

It got fixed upstream in [2] and is included in
upstream version 5.63.0.

As this may affect all users of the KDE save as dialog,
this might be considered for inclusion to stable?

Kind regards,
Bernhard
