Created attachment 109431 [details] File with chart and data to reproduce (at least on my Mac) this bug If you are editing any significantly big (in terms of amount of data) chart, then it takes some time to update values in form "Data Ranges...". If you will click anything during this time, LibreOffice crashes. How to reproduce: Create a large chart (e.g. in attachment), then mouse right-click on plot -> "Data Ranges" -> "Data Series". Now try to add (it works only if you add a new plot) a last line for "Y4" column. Set name of chart by selecting E1 cell. And now put cursor in "Range for Name" textbox. Then make really fast Ctrl-A+Ctrl-X and mouse left-button on any other plot in the list (for example). If you click before LO updates plot name to "Unnamed Series" (after removing cell address from textbox), then LO crashes.
For the test, could you give a try to last stable LO version 4.3.3?
Thanks, i tried 4.3.4, and it solved the problem. No it just does not change the name of plot in case of cell address cut.
Thank you Ilya for your feedback, I put it at WFM. Concerning the other problem, don't hesitate to open a new bugtracker. 1 bugtracker = 1 bug
