Since the update to 1.7.0 my davfs-mount crashes whenever I access it with dolphin file browser. Dolphin is still able to load the directory-content but after that I can't access any files or subdirectories after that.

Steps to reproduce
1. Mount a webdav folder with davfs-fuse
2. Access the folder with dolphin file manager
3. Try to open any file or subdirectory.

After the crash the terminal shows "transport endpoint not connected", dmesg reports a segfault:

[22463.946668] mount.davfs[28726]: segfault at 0 ip 00007f70d9b1176c sp 00007fffda724100 error 4 in libneon.so.27.5.4[7f70d9b0d000+16000]

I tried it with an completely blank folder so there is no strange file in it and it crashes nonetheless. This doesn't happen when accessing the mount with an alternative file manager like "Files".
