Calc freeze when i have non-latin fonts like this 路 文龙

When i open a clac sheet with some cells containing non-latin text, calc freeze when i try to delete a selection of rows where one of rows contain offending text. When delete only the row with offending text, it works. Is worst when i try too delete any column, freeze all the time. Selecting all sheet and try to change fonts for all cells, freeze again. I open some csv, the all page have Liberation sans font, and cell containing 路 文龙 show me Unifont font.

It’s always very important to state the version. If you are using 4.2.0 then upgrade to 4.2.1 because that sounds like a known problem in 4.2.0 that is fixed in 4.2.1

I have Version: 4.2.0.4, last version in Sabayon Linux.
Many thanks for your answer.
Now i will try to ask for upgrade of libreoffice of in my linux distribution.
