Subject: Fix segfault when rpmbuild stumbles over an empty file list.
X-Git-Tag: rpm-4.4.2.1-rc1~115
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5fdd5efb26d67e89c5d1cda51435de2896348102;p=platform%2Fupstream%2Frpm.git

Fix segfault when rpmbuild stumbles over an empty file list.
The "+ 1" is a remedy for xmalloc(0), which would return NULL.
Patch from OpenSuSE
