Thanks for the report. From the backtrace it does seem like the crash is in the epson2 backend
(In reply to Kåre Särs from comment #2) I'll report it there, if of use. However, do you have any idea *which* driver? I have all of the undermentioned installed, and don't know which is in use: > ~~~YAML > dnf search epson > Updating and loading repositories: > Repositories loaded. > Matched fields: name, summary > epson-inkjet-printer-escpr.i686: Drivers for Epson inkjet printers > epson-inkjet-printer-escpr.x86_64: Drivers for Epson inkjet printers > epson-inkjet-printer-escpr2.noarch: Drivers for Epson inkjet printers > python3-epson-projector.noarch: Python support for Epson projectors > Matched fields: summary > gutenprint-cups.x86_64: CUPS drivers for Canon, Epson, HP and compatible printers > iscan-firmware.noarch: Firmware for Epson flatbed scanners > sudo dnf install iscan-firmware.noarch > [sudo] password for RokeJulianLockhart: > Updating and loading repositories: > Repositories loaded. > Package "iscan-firmware-20241112-14.fc41.noarch" is already installed. > > Nothing to do. > sudo dnf install gutenprint-cups.x86_64 > Updating and loading repositories: > Repositories loaded. > Package "gutenprint-cups-5.3.4-18.fc41.x86_64" is already installed. > > Nothing to do. > sudo dnf install epson-inkjet-printer-escpr2.noarch > Updating and loading repositories: > Repositories loaded. > Package "epson-inkjet-printer-escpr2-1.1.49-6.1lsb3.2.fc41.noarch" is already installed. > > Nothing to do. > ~~~
Thanks! The epson2 backend is part of sane-backends (don't know the exact package on Fedora). I'll keep this report open a bit longer. I'll try to find time to investigate and be able to give good pointers to the report to sane-backends
