[Bug 28928] SQRT function not working

[Jeroen van der Vegt]

Public bug reported:
https://launchpad.net/malone/bugs/28928

Affects: gcalctool (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I can't make gcalctool compute any square-root. E.g. to compute sqrt(9) I do this:
1. start gcalctool
2. switch to 'advanced view'.
3. click on the button with the sqrt-symbol.
4. click on the button with the nine.
5. click on the button with the closing bracket.
6. click on the button with the '='.

The display is not updated, and the status bar says 'malformed
expression'. Googleing for this
(http://www.google.com/search?q=gcalctool%20sqrt) turns up similar
bugreports in Debian and Ubuntu, but I can't find the latter anymore.
Those reports suggest the LC_ALL environment variable is related, but I
can't find any relation: sqrt never works, regardless of the LC_ALL (or
any LC/LANG variable) value.
