Nevermind, it seems the segfault I reported above only happened once, I can't
reproduce it.

I am not the original bug reporter, but I've been getting the exact same crash
as he is. After updating to KDE Connect 1.3 (from the Fedora testing repos),
the crash no longer seems to happen! Also it seems to have fixed the issue
where I have to keep my phone awake to get notifications.

could have fixed it, but it was committed after the kdeconnect 1.2.1 release.

I mean, The bug is not mine, I just filed it. I have no idea where this should
go or how to request it be reassigned.

I'm just saying my whole issue has always been that when I get a slack
notification on my phone kdeconnect crashes.

Anyone out there?

Ok, so the bug is yours

Find someone else that is not me to help you fix it and debug it, i'm only
interested in the kio side since it's the only part i have some expertise, so
removing myself from this bug, if someone has a valgrind trace involving KIO
open a new bug then.

You may also want to find someone else to move it out of the frameworks-kio
since this bug that belongs to you may be in the wrong product.

I am also facing the same issue. I'm using KDE Neon User Edition with
kdeconnect version 1.2.1-0neon+16.04+xenial+build31, on laptop, and kdeconnect
app v1.7.1 on Android. I observed that if I disable 'Receive Notifications' on
KDEConnect android, then this crash of kdeconnectd does not happen on my
laptop.

go to a terminal, make sure you have valgrind installed and then run

killall kdeconnectd; valgrind /usr/lib/kdeconnectd

and try to make it crash, attach the output of valgrind

--- Comment #23 from David Mattatall  ---
I resolved that crash on load (sendAsyncData) by clearing out the config
directory. So I cannot replicate it.

There are two different stack traces on this issue. I'm not sure if the other
crash, on sendAsyncData, has actually been fixed (it might) but I'm gonna mark
it as resolved for now. Feel free to reopen if the sendAsyncData crash can be
reproduced.

This seems to have some percentage to crash when I get an alert on runscope on
my phone and I think it's sending that alert to my desktop.

Well, now it looks like it crashed in KNotification::setPixmap whereas before
it would crash in KIO::TransferJob::sendAsyncData, can you perhaps try again?

Yes please, it would be great if you could rebuild the kio package with debug
symbols

Hi it's a 100% reproducible.

Just give me the steps and I'd be happy to follow (I can even build with
symbols if you need me too). I think gentoo allows that with a flag.

David how reproducible is this for you?

Any chance you could get us a crash with more debug information?

Looks like a cras in KIO, re-assigning. There were some chnages to the
TransferJob recently, I think.
