Platform: Windows 10 1809 (believe this is a Windows-only bug)
Sigil Version: 0.9.10
Seems like a Qt bug, might be related to this bug (supposedly fixed in Qt 5.12.0?):
https://bugreports.qt.io/browse/QTBUG-27097
I did a search for "OleSetClipboard: Failed to set mime data", and not many results pop up in Google (~130).
Steps to Reproduce
I don't have a reliable test case, but I was copying/pasting between Google Docs (Chrome) + Microsoft Word 2016 + and Sigil.
Every so often, pressing Ctrl+C in Sigil would fail to copy, and this error would occur:
Code:
Error info: Critical: OleSetClipboard: Failed to set mime data (text/plain, text/html, application/vnd.oasis.opendocument.text) on clipboard: COM error 0xffffffff80070008 (Unknown error 0x0ffffffff80070008) (The parameter is incorrect.)
Sigil version: 0.9.10
Runtime Qt: 5.6.2
Compiled Qt: 5.6.2
Platform: Windows SysInfo ID 192
Every time I would press Ctrl+C, the error would pop up, and nothing would be copied to the clipboard.
If I closed Sigil and reopened, I was able to copy/paste fine.
After the error occurred, if I went to something like Notepad++ and copied plain text... it seems like I could
sometimes get Sigil working again. But once it got into this funk, restarting Sigil was pretty much the only reliable way to clear it out.
