Bug#1107962: libwebkit2gtk-4.1-0: After upgrade, breaks evolution display of messages, liferea previews

[John M.]

Other than the removal of enclosures [1], the only issue I had with
liferea was that it started showing previews on a white background
after some upgrade (i.e., the same issue evolution had with the recent
upgrade), but I just don't recall the exact version when that started
happening.

According to APT's history log, the oldest entry of webkit2gtk was
2.44.2-1+b1.

Since I only use the liferea previews to avoid watching shorts from my
YouTube-related feeds (i.e., depending on the aspect ratio of the
snapshot shown in the preview), the white backgound wasn't that much of
a problem.

Running with the DMABUF disabled, on webkit2gtk 2.48.1-3, brings back
the previews (with white brackground, that is):

   $ WEBKIT_DISABLE_DMABUF_RENDERER=1 liferea
   <sys>:0: Warning: g_atomic_ref_count_dec: assertion 'old_value > 0'
   failed
   <sys>:0: Warning: g_uri_is_valid: assertion 'uri_string != NULL' failed
   <sys>:0: Warning: g_bytes_get_size: assertion 'bytes != NULL' failed
   <sys>:0: Warning: g_bytes_get_data: assertion 'bytes != NULL' failed
   
So liferea's issue is the same as that from bug #1053199.
