bug#52651: syncthing-gtk fails to run (librsvg error)

[John Kehayias]

Thanks for the details, and I figured out the problem, though not sure of the 
fix. A similar issue was reported upstream some time ago: 
https://github.com/kozec/syncthing-gtk/issues/428 and 
https://gitlab.gnome.org/GNOME/librsvg/-/issues/210

The answer was that multiple librsvg were being used. I checked our 
syncthing-gtk (the wrapper around .syncthing-gtk-real) and there are two 
different librsvg store paths in GI_TYPELIB_PATH. Removing the first one fixes 
the problem for me, but not removing the second one.

Looking at guix gc --references for both of them shows an identical list of 
references (other than themselves). Any idea what is going on here?

This is the variable from the wrapper script:

export 
GI_TYPELIB_PATH="/gnu/store/8g4rvram1vmir3kbmizbdkbzyvfx6rqh-gtk+-3.24.30/lib/girepository-1.0:/gnu/store/qsdlm238an63wb765ldd04kn1ac3z8wc-libappindicator-12.10.0/lib/girepository-1.0:/gnu/store/q4ys65dcqg8bvndh2260h1zhydv46n1f-libnotify-0.7.9/lib/girepository-1.0:/gnu/store/wh2j9mz03vx3x6kajv0mdqgf6igd6r0j-librsvg-2.50.7/lib/girepository-1.0:/gnu/store/3pim1cxlfw07r08wsbkx35w6i2xj46i6-pango-1.48.10/lib/girepository-1.0:/gnu/store/2dza2psfbrrbvsni8jjqzzqx3hmm8kw8-librsvg-2.50.7/lib/girepository-1.0:/gnu/store/agd34525iczpyzn27zdhghy10yfiby6n-atk-2.36.0/lib/girepository-1.0:/gnu/store/pjp4d4sl00nzfdbh27qkvb47c1fb525s-libdbusmenu-16.04.0/lib/girepository-1.0:/gnu/store/a8dljzmb4w921bz3pxvfp0d2v7yzw1bb-gdk-pixbuf-2.42.4/lib/girepository-1.0:/gnu/store/dswp2mfwb56xg57903cvhwcjj1fpdhqi-harfbuzz-2.8.2/lib/girepository-1.0:/gnu/store/6p5vr2dbvrcg5yd7frjhkbm1q5mapcs0-at-spi2-core-2.40.0/lib/girepository-1.0${GI_TYPELIB_PATH:+:}$GI_TYPELIB_PATH"
