Bug 499737

SUMMARY
This is hard to describe but, I'll do my best. I'm using Konsole from git master and bash. I have a custom PS1 for bash and a large .bashrc file which I'll share if desired after I strip it of any personal info.

Sometimes when I paste some text, the start of where text input is changes.

For example, I pasted a string of text into my terminal just now and it happened.

I pasted clusha<snip the rest of the text> text in the konsole with Ctrl Shift V. However, the terminal then shows clusclusha<snip the rest of the text>. If I press the home key to go to the start of the line, I see the cursor under the second 'c' character. And if I type 'abc' it now shows clusabcclusha<snip>. That 'abc' entry is now at the start of my text, even though it shows as part way in.

This issue has been happening for a long time, but I moved to fish for a while and didn't have the issue. I recently moved back to bash to test something and ran into it again and figured it was time to report it.
