I have a QTextEdit that uses a QSyntaxHighlighter to pretty up the text. However this same issues happens with rich text.

If you select some text, right click and copy the text then try to paste it into a program like thunderbird it doesn't paste anything. If you choose "Paste without formatting" it works perfectly fine.

Anyone else have this problem? It seems like there's some problem with the mime data coming out of the text edit. This happens for 4.4, 4.3 ...

Also xcopy doesnt seem to work at all in QTextEdits (select text, then middle mouse click to paste). They both smell like bugs to me but I was hoping someone has a workaround
