This is a regression from libreoffice 3.5 in 12.04 (tested with 1:3.5.4-0ubuntu1) To reproduce: 1) Open the attached spreadsheet, which contains 1 cell with ~4k characters in it Expected results: Spreadsheet opens quickly (<2sec on my 2.4Ghz Core2Duo w/ SSD) Actual results: Libreoffice splash screen shows, libreoffice window is displayed as a gray rectangle with no content, and libreoffice window then becomes unresponsive. CPU usage is at 100% on one core. The system stays in this state for ~30sec. The document eventually opens and libreoffice functions normally. Saving documents with lots of data in a cell takes just as long as opening/reading those documents, with similar symptoms - libreoffice becomes unresponsive, one CPU core is at full utilization, etc. The amount of text in the cell is directly correlated to the length of time required to open/save the doc.
