@tobiasKaminsky @ezaquarii any idea? All reports where this happens are triggered via ThumbnailsCacheManager.

No1 Crash reported for 3.8.0

So it looks like null is handled in my version of Log.d - such logs are not printed via logcat at all.

Other implementations - perhaps, maybe - not so lucky?

@AndyScherzinger Those other crashes you mentioned - do they appear with the same stacktrace, or in various places? We could consider defensive check at Log_OC level too for all inputs.

Also fixed by nextcloud/android-library#338, but #4545 will work as well for this particular one.
