SUMMARY
If a filename contains newlines, trying to rename it causes the entire filename to be discarded, rather than highlighted for editing as usually happens.


STEPS TO REPRODUCE
1. Create a file with newlines in the filename and navigate to it in Dolphin
2. Right click on the file and select the "Rename" option

OBSERVED RESULT
The filename editing field contains only the file extension of the file. The original name of the file has vanished.

EXPECTED RESULT
Like with filenames that do not contain newlines, the original filename ought to be presented in the filename editing field.
