+Subject: [PATCH 7/7] merge newpkg->provides even when oldpkg->provides
+ existed
+
+* introduced in http://code.google.com/p/opkg/source/diff?spec=svn277&r=277&format=side&path=/trunk/libopkg/pkg.c
+* the problem happens when oldpkg provide 1 and newpkg provide 2
+  provides_count is merged to 2, but oldpkg->provides has only 1 entry
+  causing SIGSEGV:
+  pkg_formatted_field (fp=fp at entry=0x1444ce0, pkg=pkg at entry=0x120c620, field=<optimized out>, field at entry=0x7ffff7bd2abe "Provides") at pkg.c:739
+  739                           fprintf(fp, "%s %s", i == 1 ? "" : ",",
+  (gdb) bt
+  #0  pkg_formatted_field (fp=fp at entry=0x1444ce0, pkg=pkg at entry=0x120c620, field=<optimized out>, field at entry=0x7ffff7bd2abe "Provides") at pkg.c:739
