--- Comment #1 from Paul <pip....@gmx.com> --- Follow up: Just found these, the first looks very similar to the problem I observed. https://bugs.kde.org/show_bug.cgi?id=391290 The second may also be related. https://bugs.kde.org/show_bug.cgi?id=391386 I temporarily reverted back to udisks2 2.7.6 and indeed the media is actually mounted, despite the warning. Open Dolphin Insert USB stick Click to mount - error displayed Click elsewhere on a "Places" entry (Home, Downloads, whatever) Re-Click on the USB device - now shown as mounted and Dolphin displays the contents. -- You are receiving this mail because: You are watching all bug changes.
