I wonder if others experience the same behaviour:
I created a folder layout where I put the front and the back pages on separate layers. I use text boxes with justified text and adapted the letter-space in some lines in order to get more or less uniform text blocks.
This seems to work fine on first glance. Unfortunately after saving and opening the file again I end up with some lines where the last word of the previous line fuses with the first word of the next line. This of course messes up my line breaks. I can easily "repair" this by inserting a space between those two words again but I have to look very carefully to not miss any instance each time I open my file for editing.
So far I couldn't figure out when exactly this happens. It could be random but I suspect it happens when two lines with letter spacing definitions follow after another. But it doesn't happen always to the same lines.
I guess when saving and opening the XML code of the file gets interpreted slightly different resulting in losing the space between some words belonging to two different blocks of letter spacing. Maybe it only occurs if both blocks do have the same value. I imagine there is a clean-up that removes unnecessary tags losing spaces on the way.
I use Inkscape 0.92.1 r15371 on Debian GNU/Linux 9 (stretch) 64-bit with standard GNOME 3 on a Technoethical T400s (which in fact is a refurbished Lenovo T400s with Libreboot).
