I have data in a text editor which is tab-separated. I copied one line from the text editor with 44 tab-separated integer values no higher than 788 to the clipboard. I then opened a table with 100 columns in edit mode, pressed insert to add a new row and pasted the copied line. The line looks fine at the moment (before sending crash report and restarting), i.e. the paste operation seams to work on the visual layer, but then the crash report showed up.
