Hi Guix,

Epiphany (a.k.a. GNOME Web) is having trouble loading the webkit shared 
library:

Hi Jack,

what is the output of `ls -l
/gnu/store/f965xf6iwll8cj2fb45bbqkj32n8dndb-webkitgtk-with-libsoup2-
2.34.6/lib/libwebkit2gtk-4.0.so.37`?  If that's an empty file, you'll
have to repair your store.

Cheers

Thanks for taking a look. It doesnt' look empty to me:

```

Hmm, webkit changed some 15 hours ago [1].  CCing lfam to have a look
at this too.  Jack, does the parent commit [2] still work for you?

Yep, `$ guix time-machine --commit=1d1a4efd8cdac3757792cfbae92440edc5c3a802 -- shell epiphany -- epiphany`
seems to open a browser window and can browse at least one webpage. I do 
see messages like,

```
/run/current-system/profile/lib/gio/modules/libgioremote-volume-monitor.so: file too short
Failed to load module: /run/current-system/profile/lib/gio/modules/libgioremote-volume-monitor.so

```

printed to the consol though. My system has been reconfigured with the 
same commit that I originally reported.

Best,
Jack

Tags: notabug

This problem went away after I did `guix gc --verify=repair,contents`, so 
I'm closing this issue as notabug. At least it's not a bug in webkitgtk. 
Thanks for taking a look and sorry for the noise.

Best,
Jack
