The webbrowser module seems to treat URLs containing the "|" character
differently based on whether the browser is already running or not.
For instance, consider the following python script:
import webbrowser
url = "http://foo.com/bar.html?var=x|y|z"
webbrowser.open(url)
If you run this script while the browser is already running (so that
webbrowser.open creates a new tab) this behaves as you would expect,
with the given URL as an address.
However, if a browser is not already running, when webbrowser.open
creates it, it seems to interpret the "|" as a seperator character, so
that the browser will open with THREE tabs, one open to
"http://foo.com/bar.html?var=x", one to "http://y" and one to "http://z".
This is clearly a bug, webbrowser module should be smart enough to
escape the "|" character if the browser is interpreting that line
differently.
This happens in Linux with Python 2.5 and Firefox 3.0. Not sure if it
happens with anything else.
