Package: w3m-img Version: 0.5.1-5.1+b1 Severity: normal I do most of my work from within a persistent Screen session, and I regularly kill off urxvt and Xorg. This means that after the first couple of days, WINDOWID will be set (within the screen session) to a window that no longer exists.
Normally this does not bother me; w3m-img simply stops working (images
aren't displayed inline). Today, it appeared to cause a segfault.
I invoked w3m thusly:
w3m http://lists.gnu.org/mailman/listinfo/screen-users
It segfaulted -- not immediately, but a second or so after displaying
the text. This is consistent with the time it would take w3m to fetch
the inline image(s). WINDOWID was set to 8388612. Re-running the
above command caused w3m to segfault every time, after the
aforementioned short delay. w3m managed to print
4/4 images loaded
Making the terminal smaller (fewer COLUMNS and ROWS), I got
3/3 images loaded
instead. Making the terminal larger, w3m printed "HTTP/1.1 200 OK",
and the entire screen was cleared, printing "Aborted" in the top left
and the shell prompt on the next line.
Suspecting w3m-img was at fault, I tried
env -u WINDOWID w3m http://lists.gnu.org/mailman/listinfo/screen-users
This did not result in a segfault. Furthermore, it displayed the
images inline onscreen!
Attached are the output of `env' and `xprop' (after clicking on the
urxvt window). I'm not sure WHY it's segfaulting; hopefully I've
provided enough information. I am running a custom compilation of
urxvt from CVS:
