When I start a recent daily build of LO, I get: warn:configmgr:28259:28259:configmgr/source/xcuparser.cxx:159: bad set node <prop> member in "file:///home/eyalroz/.config/libreofficedev/4/user/uno_packages/cache/registry/com.sun.star.comp.deployment.configuration.PackageRegistryBackend/lu8080g1ofb.tmp/Addons.xcu" on the console. I don't believe this is due to some add-on I installed myself, so - it's LO itself that's responsible for putting that Addons.xcu files there. Thus - either the file format is fine, in which case there's a parsing bug; or the parse is fine, in which case LO is deploying an invalid file.

Could you give a try at https://wiki.documentfoundation.org/QA/FirstSteps#Corrupted_user_profile ?
(In reply to Julien Nabet from comment #1) > Could you give a try at > https://wiki.documentfoundation.org/QA/FirstSteps#Corrupted_user_profile ? I might, but - I don't believe my profile is corrupted. LO works well enough. Would you like me to attach that file?
(In reply to Julien Nabet from comment #1) I looked at the instructions, and they're just about using a new profile. But I see the bug with my current profile. If I remove the file, the bug will not manifest. So I don't see how that would help.
LO doesn't create Addons.xcu files on its own. This file is likely coming from an extension you tried to install, and it has a wrong format there.

But the error is not from a package, it's from the cache; plus, the "package" in question is: com.sun.star.comp.deployment.configuration.PackageRegistryBackend so AFAICT it doesn't come from a third-party source.
Created attachment 170352 [details] Addons.xcu file triggering the messages
OK, so the extension in question is TexMaths 0.48.2. I downloaded it from https://extensions.libreoffice.org/en/extensions/show/texmaths-1, and could reproduce the same log. Try to disable this extension, and see how that warning goes away. I looked at the Addons.xcu file of this extension, and it indeed has invalid format. It seems that this extension tries to keep working also with AOO, which changed how toolbars are defined in Addons.xcu, and there was a decision on the LO side to not follow this incompatible change. So LO is complaining about the AOO-specific definition that it doesn't understand.
