A tree of maildirs: $MAILDIR_ROOT/<maildir> To replicate: rm -r $MAILDIR/tmp Result: No folders are shown (not even the ones with correct subdirs) I hit this issue because I transfer my maildirs with Mercurial. My workaround is adding a .keep file into every subdir, but that’s not nice. Reproducible: Always
Fixed in 4.10.2.
