SUMMARY
Clipboard applet becomes unusable if I entered something in the filter and then clear the history, because the filter field is then disabled but the filtertext is still displayed and active

STEPS TO REPRODUCE
1. have some entries in the clipboard
2. enter something in the clipboard filter field, like "xyz"
3. clear the history (button beside filter), the filter-textfield becomes disabled
4. copy some new things (which do not match xyz)
5. the clipboard remains empty because the filter is still active, but the filter-textfield is still disabled, also no clear-filter-button
