Downloading PDF crashes WALC

[gcaria]

Hi,
I'm using WALC on Ubuntu 20.04 and when clicking on the download button for a PDF document, WALC just dies and needs to be reopened. Please let me know if I can provide more information.

Please tell me the installation method (AppImage or snap?) and the app version

[Zzombiee2361]

Now can you run WALC from terminal, reproduce the bug, and paste the terminal output here? Make sure to close WALC first

I cannot reproduce it on my side on Ubuntu 20.04, Please check if there are any pending OS updates and then:

Follow these steps:

1. ensure that WALC is closed
2. sudo /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/gdk-pixbuf-query-loaders --update-cache
3. restart WALC and try again.

IF this doesn't solve the issue, provide output of these two commands
ls -l /usr/lib/gdk-pixbuf-2.0
AND
ls -l /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0
Separately

[gcaria]

Unfortunately that didn't solve the issue,

❯ ls -l /usr/lib/gdk-pixbuf-2.0
ls: cannot access '/usr/lib/gdk-pixbuf-2.0': No such file or directory
❯ ls -l /usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0

Oh. then I will have to get back to you if I find any solution to that. But this is an upstream bug of electron. A lot of application seems to be affected by it.

Meanwhile, if you find any solution or workaround do post it here.

[gcaria]

Thanks for looking into this @cstayyab, I will keep you posted if something comes up

[gcaria]

It's me again, I found that also clicking on the "Photos and videos" button (after clicking on "Attach") causes WALC to crash. Is this a related issue to the above one?
