Happens. Same error message "too many open files" appears in log file repeatedly, designer-qt4 crashes at file open dialog. Log file is attached. Then I repeated same with strace and to gain clue which system call gets repeatedly called but now the crash does not happen any more, file open dialog opens just fine. Quite mysterious. According to log file akonadi indexing server gets started in the background and there seems to be bug report from year 2011 https://bugs.kde.org/show_bug.cgi?id=275261 where steps and symptons are slightly different but partly same story - if akonadi misbehaves, maybe strace slows it down so that there is still one free file descriptor left at the time I hit "file->open" from menu? Log file with strace is in http://katiska.org/~costello/designer-qt4-strace.log.gz I did not attach it due to size of 434k but "clean nfs home" example is attached. Also, this may have started happening after upgrade big kde upgrade including kde-baseapps-bin:amd64 (4:16.08.0-1, 4:16.08.2-1) but I'm not certain, because I don't need to use designer-qt4 very often. Other qt(5)-based apps work just fine. -- Antti
