Bug 384856

Hello KDE people,

After years, with help from the LFS/BLFS team, I managed to compile quite a lot of KDE - yay, go me! \o/

I even got konsole to work, or at the least, to start up, using this version:

https://download.kde.org/stable/applications/17.08.1/src/konsole-17.08.1.tar.xz

Konsole starts fine and I can use it. The default is white background and black font but I prefer black background and white font. So I tried to change the profiles ... well.

First thing, the profiles list is empty. I probably did something wrong but I
think it may be useful if, in the event that the profiles list is empty, perhaps some widget or some other way, right button press, or whatever, can inform a user a bit why this is the case. I understand that the KDE apps will default casual users rather than people who compile from source but ... right now I have ABSOLUTELY no idea as to why the profile list is empty. Anyway, I guess I may figure out one day, but for now, this report is actually about something afterwards.

I realized that the profile list was emtpy but one can create a new profile list. So I tried this.

But when I clicked on the white rectangular box next to the "Background" slot, konsole crashed.

The error dump on the commandline is:

QStandardPaths: wrong ownership on runtime directory /Depot/Temp, 1000 instead of 0

(konsole:15836): GdkPixbuf-WARNING **: Bug! loader 'png' didn't set an error on failure

(konsole:15836): Gtk-WARNING **: Could not load a pixbuf from icon theme.
This may indicate that pixbuf loaders or the mime database could not be found.

Gtk:ERROR:gtkiconhelper.c:493:ensure_surface_for_gicon: assertion failed: (destination)
Aborted

Now, I am pretty sure that the error is on my side ... I have some libpng and gdk-pixbuf related problem... probably also via gtk (although actually, almost all of the gnome-related programs, including evince, that I use from the commandline, do work fine). So the error is not so much about a problem WITHIN kde konsole. But I am still annoyed that kde konsole just crashes.

So here is my suggestion to change this:

- IF an error like the above happens, such as when someone can not find a loader for
png, then rather than crash, konsole could notify about the error; on the commandline
of course, but also perhaps within the konsole application. A simple pop-up widget
that may be triggered could suffice or perhaps even better, some in-app notification
within konsole. Either way, I think notification is better than flat-out crash.

Feel free to proceed with this bug report in any way that you wish to, including to
close it at any moment in time.

PS: Being able to set background and foreground on the commandline would be neat, then I could just start konsole like so:  "konsole --bg black --fg white", or something like that. Right now it seems as if profiles are mandatory. Not sure why but that wasn't my decision anyway. I su ppose that I could probably create
some profile on the commandline via ruby scripts ... but being fairly lazy, I am not sure
I'll go just through that part only to have black background and white colours again... but
who knows.

PSS: I actually also use a second konsole, from kde4... that one is at /usr prefix; the
new konsole is in /Programs/Konsole/17.08.1 - no idea if that matters or not, I think
it should not, since the error is related to gdk/gtk rather than konsole. But I mention
it just for sake of completion. I am also not entirely sure why konsole attempts to use
a gtk-dialog, perhaps some kde-dialog is unavailable? I have no idea... I have not 
finished compiling all of kde so far, neither plasma... but I'll have a look how this
goes in the coming weeks.
