backslashes get stripped from $ signs

Hi guys,
using pyblosxom 1.5 from git
with an very simple entry like the following:

$ cat entries/backslash.txt 
backslash
PS1="\u@\h \[\$foo \]\W\[$RST\] \$"
<![CDATA[
PS1="\u@\h \[\$foo \]\W\[$RST\] \$"
]]>

PB emits html code as follows:
(...)
PS1="\u@\h \[$foo \]\W\[$RST\] $"
<![CDATA[
PS1="\u@\h \[$foo \]\W\[$RST\] $"
]]>
(...)

notice how the backslashes before the $'s are now gone.
i disabled *all* plugins and use the default (plain) parser.
blog-encoding is utf-8
I have this issue with both static rendering and "normal mode".
I use a regular html flavour and can reproduce it even like this:

$ cat flavours/html.flav/story 
$(body)


anyone an idea?
