That sounds like a system problem.

Unlikely, Dolphin is not using any access method on such a low level that it 
would matter which filesystem module is handling it.

No, see above.

Again, see above.
Dolphin is just using system API to access local files. The system takes care 
of accessing the actual file system through filesystem modules.

Sounds again like a system problem.
If you cannot even mount it, how would any user space program access it?
