I use Ubuntu 17.04. Every time I use gedit command in terminal I get a warning.

$ gedit sample.cpp
(gedit:6496): Gtk-WARNING **: Allocating size to GtkPaned 0x55bb7be10780 without calling gtk_widget_get_preferred_width/height(). How does the code know the size to allocate?

What is the cause of these warnings? Does it affect the system in any way? Is there any way to resolve them or should I just ignore them?

Thanks.

    Ubuntu 17.04 reached EOL on 13-Jan-2018, was not (& won't be) patched for Meltdown, Spectre etc so I'd suggest release-upgrading to a supported release of Ubuntu (ie. 17.10). It's also now off-topic on this site. As to your question, I'd just ignore them as warnings are mostly for development (debugging etc) use. – guiverc Feb 19 '18 at 11:53
  • @ guiverc Got it. So these warnings do not shoot up in 17.10 or 16.04 LTS or 14.04 LTS? – Edmund Fitzgerald Feb 19 '18 at 11:58
  • :) there is a chance that you won't see the messages in all three (the EOL has nothing to do with message). I read the message as a coder putting out a message to blame someone else should it fail.... (failure would require a hugely invalid value probably though [to cause overflow]) – guiverc Feb 19 '18 at 12:02

    It's just a warning, not an error, so it can usually safely be ignored. I recommend you to use xdg-open to open files in their default application though, which should launch Gedit for all text files. It also runs in background and immediately releases your terminal again. – Byte Commander Feb 19 '18 at 12:06
  • @ guiverc Wasn't intending to blame. Was just asking. In fact, since the warnings do not mean anything significant, I can afford to wait till April for 18.04 LTS. – Edmund Fitzgerald Feb 19 '18 at 12:07
  • You can look at my answer here as well as the others in the same Q&A. – DK Bose Feb 19 '18 at 12:16
  • It's a bug in gedit you can ignore. A python developer was reported this bug on January 18 and fixed it January 19. If only gedit developers moved as quick: https://github.com/Cimbali/pympress/issues/53 – WinEunuuchs2Unix Feb 19 '18 at 15:03
