Windows 11, and try on ubuntu to, its the same outcome. SUMMARY STEPS TO REPRODUCE 1. scan an image with epson in tiff 16bit 600dpi, app xsane 0.999 2. open file in showfoto 3. save file as new file (ctrl+shift+s) 4. now convert to jpg with First the one xsane made from the scan, the file raw_scan_001.tiff we open in showfoto and save: arkiv@Arkiv-PC5:~$ convert "/home/arkiv/Billeder/OCR/raw_scan_001.tiff" -quality 85 "/home/arkiv/Billeder/OCR/raw_scan_001.jpg" arkiv@Arkiv-PC5:~$ All good, now the one from xsane scan saved with ShowFoto, and its the same with the editor in Digcam, both linux on ubuntu and win 11 raw_scan_001_save1.tiff arkiv@Arkiv-PC5:~$ convert "/home/arkiv/Billeder/OCR/raw_scan_001_save1.tiff" -quality 85 "/home/arkiv/Billeder/OCR/raw_scan_001_save1.jpg" Afbrudt (SIGABRT) (smed kerne) OBSERVED RESULT no output of the jpg file it fails. i try to clean meta but then got other error, i then try to generate new file, and now i can make jpg but still with error Here i try to fiddel with it together with chatgpt i just try this it gives an output jpg but its still gives the error but now i get an jpg file, just not sure if its ok or not, so it looks like its some meta and some other stuff and now this one is left C5:~$ convert /home/arkiv/Billeder/OCR/raw_scan_001_save1.tiff -depth 16 -compress none /home/arkiv/Billeder/OCR/b0001_clean.tiff Afbrudt (SIGABRT) (smed kerne) arkiv@Arkiv-PC5:~$ exiftool -all= -overwrite_original "/home/arkiv/Billeder/OCR/raw_scan_001_save1.tiff" Warning: [minor] Can't delete IFD0 from TIFF - /home/arkiv/Billeder/OCR/raw_scan_001_save1.tiff 1 image files updated arkiv@Arkiv-PC5:~$ convert /home/arkiv/Billeder/OCR/raw_scan_001_save1.tiff -depth 16 -compress none /home/arkiv/Billeder/OCR/b0001_clean.tiff convert-im6.q16: Unknown field with tag 11 (0xb) encountered. TIFFReadDirectory' @ warning/tiff.c/TIFFWarnings/905. EXPECTED RESULT an output of my jpg file SOFTWARE/OS VERSIONS Windows: 11 ADDITIONAL INFORMATION i all so found out that in ubuntu its best to start the app with QT_QPA_PLATFORM=xcb showfoto else its really unstable and the editor window is laggy and some time app crash but its better when start with the command abow.
The crash appears in ImageMagick CLI not Showfoto. We don't expect fix ImageMagick code (:=))). Is the tiff to jpg convertion work in the Gimp ?

I tested it here with a TIFF from XSane via an Epson scanner. Using ImageMagick "convert" never caused a crash. My ImageMagick "convert" version is 7.1.1-44 Q16-HDRI x86_64 22688. Maik
