[Synthlight]

Pre-submission Checks

• I checked for similar issues, but could not find any. I also checked the closed issues. I could not contribute additional information to any existing issue.
• I will take the time to fill in all the required fields. I know that the bug report may be dismissed otherwise due to lack of information.

Describe the bug

The command I'm running is:
owncloudcmd --trust $HOME/bin https://user@[email protected]/owncloud/remote.php/dav/files/username/bin
(I've redacted sensitive info.)

This results in a segmentation fault with Could not load plugin: not existant or bad metadata "owncloudsync_vfs_off". (Full log below.)

I was able to find an older closed issue for v3.0: #10185
I didn't see a "re-open" button and was unsure of the policy, so made a new one.

I can't tell you what version I had before since I don't see it in the repo anymore, but updates had been run on the VMs last week and it was working then.

Expected behavior

I expected the command to succeed and files to be synced.

Steps to reproduce the issue

Just run owncloudcmd --trust $HOME/bin https://user@[email protected]/owncloud/remote.php/dav/files/username/bin.
System info below as I presume that's related.

[TheOneRing]

@fmoc btw the about line does not mention the plugin dir because the define OC_PLUGIN_DIR is only set for the platform_unix.cpp

client/src/libsync/theme.cpp

Lines 417 to 421 in 1ca1caf

	#if defined(OC_PLUGIN_DIR)
	const QString pluginDirComment = QCoreApplication::translate("ownCloudTheme::pluginDir", "Plugin dir: %1%2").arg(QDir(QCoreApplication::applicationDirPath()).filePath(QStringLiteral(OC_PLUGIN_DIR)), br);
	#else
	const QString pluginDirComment = QString();
	#endif

@TheOneRing @fmoc 4.1 candidate? otherwise 5.0…
