Hello,
after running a fairly large update today gimagereader-gtk fails to start with the following error msg:
$gimagereader-gtk %U
gimagereader-gtk: symbol lookup error: gimagereader-gtk: undefined symbol: _ZN6PoDoFo8PdfImage14LoadFromBufferERKN3tcb4spanIKcLm18446744073709551615EEE
I uninstalled (-Rs) and reinstalled, no change.
I also installed gimagereader-qt6, and I get the exact same error when starting from cli:
$gimagereader-qt6 %U
gimagereader-qt6: symbol lookup error: gimagereader-qt6: undefined symbol: _ZN6PoDoFo8PdfImage14LoadFromBufferERKN3tcb4spanIKcLm18446744073709551615EEE
I use gimagereader several times a week, and it has been working without hicuup until today, so I am assuming it is today’s update.
I did run a second update later in the day and there was another kernel update, but after rebooting the issue remains unchanged.
Any help or suggestions to solve, appreciated. Thks.
First: @murkrell welcome to the forum! 
If you think the update is the reason for the error I would do following:
Run the command yay -Qi gimagereader-gtk and check for packages it depends on. Then check your /var/log/pacman.log if one of the depending apps was updated today. If yes this may be the culprit.
To test this you can run the command sudo downgrade <name_of_the_package> and then check again if gimagereader is running fine. If not then run the normal update again and you have to wait till the error is fixed upstream.

@marteng69, thanks
@murkrell, after update i got same error;
from the error you might notice that the problem is related to PoDoFo library’s PdfImage::LoadFromBuffer function;
that’s why by downgrading podofo library:
$ sudo pacman -U /var/cache/pacman/pkg/podofo-0.10.3-1-x86_64.pkg.tar.zst
you might experience the other error:
error while loading shared libraries: libxml2.so.2: cannot open shared object file: No such file or directory
which could be solved by installing libxml2-legacy:
sudo pacman -S libxml2-legacy
in my case i was able to run gimagereader-qt6
have a good day, bro
