Some strange behaviour takes place in Microblogging plasmoid right after the startup of Plasma (or soon after that). If I type some text to message text box, then cut and paste it, it is painted on black background and the text color is black either, i.e. it's invisible (see the screenshot). Taken a look at the code I found that the text box is Plasma::TextEdit object and most possible cause seems to be that on cut (Ctrl+X or whatever) it tooks toHtml() of the text and then pastes it some illegal way.

If I remove all the text from the box with Backspace and start to type and Cut/Copy/Paste again everything works correctly.

Reproducible: Always

Steps to Reproduce:
1. Start Plasma (start KDE, for instance).
2. Type some text in message text box of Microblogging plasmoid.
3. Ctrl+X it and Ctrl+V it.
4. Notice that it's painted with black foreground and background color and you can't read it.
5. Try to type some text further. It's painted the same way. Try to paste some text from another source. It's still painted just the same.
6. Clear the content with Backspace.
7. Type some text and Cut/Paste it. Notice that it's not painted incorrectly anymore.
