** Description changed:

+ The fix:
+ https://anonscm.debian.org/git/pbuilder/pbuilder.git/commit/?id=bf1acdc
+ 
  [Impact]
  
  The remove_packages() function in pbuilder-modules contains:
-     if (dpkg -s "$pkg" 2>&1)>/dev/null ; then
- This obviously must 
-     if ($CHROOTEXEC dpkg -s "$pkg" 2>&1)>/dev/null ; then
+     if (dpkg -s "$pkg" 2>&1)>/dev/null ; then
+ This obviously must
+     if ($CHROOTEXEC dpkg -s "$pkg" 2>&1)>/dev/null ; then
  
  This causes remove_packages() to try to remove packages that are not
  present, actually making the function not working at all in some
  circumstances, leading to crashes.
  
  [Test Case]
  
-  * get a sarge chroot, or anyway around that time
-  * assuming you have pbuilder installed on the host and not in the chroot, 
run:
-        pbuilder u --removepackages pbuilder
+  * get a sarge chroot, or anyway around that time
+  * assuming you have pbuilder installed on the host and not in the chroot, 
run:
+        pbuilder u --removepackages pbuilder
  
  [Regression Potential]
  
-  * for yakkety, no potential regression, this is a targetted fix.
