Hi, In the bug report https://bugs.freedesktop.org/show_bug.cgi?id=54719 I describe a crash in Calc 3.6.1.2 and 3.6.2.0+ when deleting a row in a sheet with conditional formatting. Markus is in copy of the bug report. Best regards. JBF -- Seuls des formats ouverts peuvent assurer la pérennité de vos documents.
