Hi Wladimir, thank you for confirming that this is resolved on 6.3.4. Considering how rare a scenario this is, I’m going to say it’s not worth an SRU to 18.04.
For those experiencing minor issues such as this on earlier versions of Ubuntu, I recommend installing the LibreOffice snap. It’s not only up to date but officially supported as well. snap install libreoffice snap run libreoffice ** Changed in: libreoffice (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1862021 Title: opening .rtf file renamed with .doc extension crashes lowriter Status in libreoffice package in Ubuntu: Fix Released Bug description: Ubuntu 18.04.4, LibreOffice 1:6.0.7-0ubuntu0.18.04.10 (all i386, not amd64, also without JRE to avoid crashes on LP:1699772) We received some files with .doc extension which actually were in RTF format (as 'file' showed) When we tried to open these files, lowriter crashed every time. Abiword opened the same files fine. Probably it detects their type by content, not only by extension. For LO, the cure was to rename them manually from .doc into .rtf, then lowriter could also open them without crashing. Probably some Abiword logic of file type detection should be borrowed into LO to improve user's convenience. Later today I will add my results from LO 1:6.3.4-0ubuntu1 which I test on my home system as a part of upcoming Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1862021/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
