Bug#786590: dwb: segfaults with libwebkitgtk-3.0-0 2.4.9-1
Hi everyone who encountered this bug on Debian, I have performed some shallow debugging after I encountered these dwb crashes myself (Debian stretch x86-64, webkitgtk 2.4.9-3, dwb built from the most recent git snapshot). At the first glance, the culprit is dwb (namely adblock.c), not webkitgtk. As a temporary solution, you may disable adblocker by setting the option "adblocker" to false (or just :set adblocker false) - that should fix the constant crashes at every page. (Of course it's better to run dwb on a clean session or use -R option from the beginning, otherwise dwb will try to restore the session and the crash will hit you before you ever have a chance to disable the adblocker). The segfault originates from the function "adblock_apply_element_hider" in adblock.c: due to some reason, one of the elements of the list VIEW(gl)->status->styles (a local variable) is a corrupted pointer; when the function attempts to apply WEBKIT_DOM_NODE typecast on it, this leads to a segfault from a GObject typecasting internal. No idea yet who is responsible for corrupting the pointers (adblocker or maybe webkit); I'll try to examine the logic of adblock.c a bit later. By the way, dwb source distribution has a primitive backtrace script, tools/backtrace.sh; you will probably want to attach its output to the bug report. Thanks, Oleg

Hi Sebastian, as far as I can see the only other browser depending on libwebkitgtk-3.0-0 is xombrero, and I can not reproduce the issue with it.
