SUMMARY
.blacklist(Brush, Gradation, SeExpr, etc) cannot handle paths that contain some characters.

Character examples:
Hiragana (あいうえお, etc)
Katakana (アイウエオ, etc)
Kanji    (甲乙丙上中下一二三, etc)
Hangul   (안녕하세요, etc)
Cyrillic (αβ γΔΕΖ, etc)

STEPS TO REPRODUCE
*Let's take SeExpr as an example.
1. Create a SeExpr with a name containing the above characters.
2. Delete it.(Trashcan icon)
3. Restart Krita.
4. Make sure that it has not been removed from the SeExpr list.

OBSERVED RESULT
It is not removed from the list.

EXPECTED RESULT
It will be removed from the list even after restart.
