tumblerd crashed with SIGSEGV (memory leaks detected)

[Paul Dufresne]

Had open a pdf in Thunar and was reading it for about 2 mins when the error happened.

Had reported a similar bug previously, but LBRY was opened, and I was kind of waiting it reproduce to avoid my cryptographic information linked to LBRY to be made public (I frankly not know how much dangerous it is to make public).

Will try to link the 2 bugs.

Similar bug with LBRY information I am unsure I want to make public is bug #1923164 .

[Paul Dufresne (dufresnep)]

bug #1168558 reported in 2013 is similar by the fact that "Stack memory exhausted"

[Paul Dufresne (dufresnep)]

bug #1290041 reported in 2014 is similar by the fact that "Stack memory exhausted"

[Paul Dufresne (dufresnep)]

Well, it should not be linked because the bug is closed (about sparse file video mp4), but I do too have mp4 video files without thumbnails... and because it was causing it to use a lot of memory (stack memory could be something else) I mention it as a remember: https://bugzilla.xfce.org/show_bug.cgi?id=12259#c6

[Paul Dufresne (dufresnep)]

Also, I have run thunar in a terminal and got:
paul@jacko:~$ thunar
ThunarThumbnailer: Queue failed: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying

which is kind of weird... kind of the opposite of the bug... making tumbler not usable by thunar.

[Paul Dufresne (dufresnep)]

previous post is much harder to read as a message than the original... attaching valgrind2.txt with same information

[Paul Dufresne (dufresnep)]

I have a 17 Mb valgrind3.txt generated by:
valgrind --leak-check=full --show-leak-kinds=all /usr/lib/x86_64-linux-gnu/tumbler-1/tumblerd 2> valgrind3.txt

I don't know if it is really usefull to debug.
