SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Downloaded PDF from https://www.lbhf.gov.uk/sites/default/files/section_attachments/medical-assessment-form.pdf 2. Click "Show Forms" in order to fill form 3. Enter information, click File > Save OBSERVED RESULT Okular crashes so fast that I wasn't at first sure that it had time to save the data. Opting to submit a bug report also results in the debugger crashing. EXPECTED RESULT Okular should save the data and allow me to continue entering data? SOFTWARE/OS VERSIONS Windows: none macOS: none Linux/KDE Plasma: Linux kernel 5.10.0-18-amd64/Debian 11/ (available in About System) KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION Operating System: Debian GNU/Linux 11 KDE Plasma Version: 5.20.5 KDE Frameworks Version: 5.78.0 Qt Version: 5.15.2 Kernel Version: 5.10.0-18-amd64 OS Type: 64-bit Processors: 4 × AMD A10-5700 APU with Radeon(tm) HD Graphics Memory: 14.9 GiB of RAM Graphics Processor: AMD ARUBA Also, after the 1st crash I reopened the file in Okular and my data appeared to have been saved. The 2nd time I clicked File > Save there was no crash, but the 3rd time it did crash. I also note that the font size appears to change according to how much text is entered, until I click Show Forms again. This, however, does not appear to crash the application.
