Second thoughts...
The --no-markup option prevents zenity from interpreting \n which makes
the dialog hard to read in most cases. So only adding --no-markup is not
a viable solution.
As a possible alternative I played with sed() a bit. The script includes
this line:
TEXT="$PARA1\n\n$(fold -s $ERR)\n\n$PARA2"
My thought is to add a new line right after that. Something along these
lines:
TEXT=$(printf '%s' "$TEXT" | sed 's/</\</g')
which would replace all occurrences of '<' with '<'. Can you please
test that and see if it helps in your case.

Bug description:
I modified my ~/.profile to call "logger". This resulted in in
producing some output on stderr like
```
<13>Jul 11 13:02:46 /usr/sbin/lightdm-session[1408]: profile sourced ...
```
This showed an empty zenity prompt.
Logs suggest zenity was failing because it was treating `<13>` as
pango markup.
```
from markup due to error parsing markup: Error on line 3 char 6: “13” is not
a valid
```
We should not assume the error message strings contain valid markup,
since their source is unknown.
