Comment 1 for bug 275537

I can confirm this. I've just tried to build a source package that I have moved to a folder with a space in it, and this is the output I get from PBuilder:

Copying source file
awk: BEGIN{p=0} /^$/ {p=0} /^.*:/ {p=0} {if (p){print "/tmp/cheese
awk: ^ unterminated string
    -> copying [/tmp/cheese 1/cheese_2.23.91-0ubuntu1.dsc]
Extracting source
dpkg-source: failure: cannot open cheese: No such file or directory
pbuilder: Failed extracting the source
