When copying a sequence of characters containing "ö", "ä" or "ü" from a website in Firefox and pasting it into a KeePass2 password field, KeePass2 and/or Ubuntu crashes. The latter depends on whether it's the "Open Database" dialog or the password field of a database entry. (No problems, when using Chrome) When pasting into the "Open container" dialog, I get a "KeePass - Fatal Error" window, saying > A fatal error has occurred! > > An extended error report has been copied to the clipboard. > > Cannot access a disposed object. > Object name: 'KeePass.UI.CustomListViewEx'.

I'm using Ubuntu 20.04, Firefox 84.0 and KeePass 2.44. For me it's unclear whether it's related to Ubuntu, Firefox or KeePass or multiple of them. So far, I tried to compare the clipboard content with Chrome (87.0.4280.88). When copying the lower case "ö" in the first sentence of https://en.wikipedia.org/wiki/%C3%96 using Firefox and Chrome I get two different results, using shell command > xclip -o -noutf8 | xxd This returns 0xc3b6 for Chrome and 0xf6 for Firefox. 0xc3b6 is "ö" encoded with utf-8, but 0xf6 is simply the un-encoded unicode code-point for "ö". But I found no information, how the clipboard content should be encoded. Nor do I know if the above approach for comparing clipboard content is reasonable. So maybe someone can tell me, where I should file a bug report. Thank you.
