Weird startup problem

I have Slackware64-Current here and got the following problem recently after an upgrade. I decided to post it because the actual error message was quite unrelated to the problem.

Browser Version Version 1.75-175
Problem: Not starting. Running in an xterm, I got this error

[6295:6317:0228/164315.617008:ERROR:object_proxy.cc(576)] Failed to call method: org.freedesktop.DBus.Properties.Get: object_path= /org/freedesktop/portal/desktop: org.freedesktop.DBus.Error.InvalidArgs: No such interface âorg.freedesktop.portal.FileChooserâdec@ebony:~$

I was trying to debug firefox, which was giving an error about libxul.so. That links to libsqlite3.so.0, which links to 3 libicu* libraries provided by the icu4c package. It transpires my icu4c ( icu4c-76.1) had been updated, but my sqlite version had not. My version of sqlite-3.46 had been built against icu4c-74, which was no longer installed. Updating my sqlite version also fixed brave browser’s error! How all that relates back to the error message is beyond me.

This may be useful in the furure, as the error message I found positively misleading.
