kate does not show newline inserted at the beginning

[Sergei Ivanov]

This was already reported as bug #146306 (which is closed as unreproducible). I have this issue on Gutsy with current kdelibs (kdelibs4c2a-3.5.8-0ubuntu3.1).

To reproduce: run Kate on a file with more lines than kate's window has (this is essential), then hit Enter at the beginning of the file. Kate inserts a line but does not display it (until you hit Uparrow or something similar).

This also happens if it is not the beginning of the file but the beginning of the visible part. You can hit Enter several times and still see no effect (as if the key did not work). Same behavior with Kile instead of Kate.

The bug was introduced at some point between KDE 3.5.5 and KDE 3.5.8. The following patch fixes it.

Thanks for this. I can confirm the bug but this patch doesn't seem to solve it for me.

If my copy-pasting broke the patch, see the attached one here. It still works for me, now with kdelibs-3.5.8-0ubuntu3.2.
I apply it before running anything from debian/rules. Here is what I do:

apt-get source kdelibs
patch -d kdelibs-3.5.8 -p1 < newline.patch
cd kdelibs-3.5.8
debuild -us -uc -b
sudo dpkg -i kdelibs4c2a_3.5.8-0ubuntu3.2_i386.deb

Note that the affected fragment is in some obscure shared library which may be loaded via dlopen(). If you install the new version in /usr/local, the old one could still be used. It also makes sense to restart KDE to get rid of preloaded stuff (it works for me without restarting but generally KDE does not support live upgrading).

My bad, I installed through upgrade and didn't notice that kdelibs4c2a was held back. Yes, I can confirm that it works (using 4:3.5.8-4ubuntu6), I'm subscribing u-m-s in case they care to include this with the next update, but note that this was fixed for KDE 4 (http://bugs.kde.org/show_bug.cgi?id=146300).

Thanks. I hope KDE3 will be packaged and supported for a while (at this stage KDE4
is far from being usable for real work).

This bug was fixed in the package kdelibs - 4:3.5.8-4ubuntu11
