Warning from GTK

Node Development
1

Hi all,
I am running KNIME 3.7.0 on CentOS 7.0 and keep on getting following warning from GTK

(KNIME:12075): Gtk-CRITICAL **: gtk_box_gadget_distribute: assertion ‘size >= 0’ failed in GtkScrollbar

It is nothing serious but it is annoying and here already discussed
https://bugs.eclipse.org/bugs/show_bug.cgi?id=538000

I wonder whether it might proper of CentOS or it is something which could be eventually corrected.
Best regards
Andrea

Hi @agiani99,

I am getting the same error on Ubuntu 18.04:
(KNIME:28232): Gtk-CRITICAL **: 15:00:01.375: gtk_box_gadget_distribute: assertion 'size >= 0' failed in GtkScrollbar
and also another warning:
(KNIME:28232): Gtk-WARNING **: 15:00:01.706: Negative content width -1 (allocation 1, extents 1x1) while allocating gadget (node trough, owner GtkProgressBar)

So I guess it is not only CentOS. Looking forward to having this issue resolved.
Best regards,
Johannes

I’m also getting this on Ubuntu 18.04.

4

same error on ubuntu 20. Is there any work arround to fix it?

5

Confirm @gbottari: same error on Ubuntu Focal 20.4
Is the Knime community at all engaged with Linux???

6

I am also seeing this error cluttering the terminal on Ubuntu 20.04.

Any help would be really appreciated.

Also with Centos 7 with KNIME 4.7
Any solutions ???

thanks,
mike

The same applies to me, with Knime 4.7 and Ubuntu 22.04.

If I well understood, it seems the bug is between GTK and Eclipse… Have a look on this quite old and still opened issue : GTK 3.22 scrollbar errors when resizing GtkTextView in a GtkScrolledWindow (#210) · Issues · GNOME / gtk · GitLab

I can only advise patience (or lot of motivation and solid skills in Java, GTK and C).
