RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Laszlo Ersek 2013-06-25 14:26:07 UTC 
*** Description of problem:
In order to review and test the qemu series at <http://lists.nongnu.org/archive/html/qemu-devel/2013-06/msg00959.html>, I need to run "msiextract" on a Windows installer file.

I installed gcab-0.4 and msitools-0.92 from source. When I run

  msiextract vsssdk.msi

I get

  ** (msiextract:30909): CRITICAL **: libmsi_istream_new: assertion `dup'
  failed

  (msiextract:30909): gcab-CRITICAL **: gcab_cabinet_load: assertion
  `G_IS_INPUT_STREAM (stream)' failed

Turns out this is a known problem in libgsf (a dependency of msitools); an unshipped upstream patch is available from Paolo Bonzini. See <https://bugzilla.gnome.org/show_bug.cgi?id=689706>.

*** Version-Release number of selected component (if applicable):
libgsf-1.14.15-5.el6.x86_64
libgsf-devel-1.14.15-5.el6.x86_64
libgsf-gnome-1.14.15-5.el6.x86_64
libgsf-gnome-devel-1.14.15-5.el6.x86_64

*** How reproducible:
100%

*** Steps to Reproduce:
1. Download "setup.exe" from <http://www.microsoft.com/en-us/download/details.aspx?id=23490>.
2. Extract "vsssdk.msi" from "setup.exe" using the script in <http://lists.nongnu.org/archive/html/qemu-devel/2013-06/msg00966.html>.
3. Try to extract "vsssdk.msi" with msitools-0.92, built against libgsf-1.14.15-5.el6.

*** Actual results:
Assertion failure.

*** Expected results:
Extraction should work.

*** Additional info:
The brew build <https://brewweb.devel.redhat.com/buildinfo?buildID=252310> seems to backport this patch. However it only references a gnome BZ, not a Red Hat BZ.

The fix in that build has also not been pushed to dist-git.
Comment 1 Paolo Bonzini 2013-06-25 14:45:12 UTC 
The patch is not unshipped, just not backported to RHEL.
Comment 2 Laszlo Ersek 2013-06-25 14:51:10 UTC 
Is it available in a tarball release? I was working from <https://wiki.gnome.org/action/recall/msitools?action=recall&rev=6>.
Comment 4 Paolo Bonzini 2013-06-25 15:29:18 UTC 
Yes, it is in 1.14.26 (see https://git.gnome.org/browse/libgsf/log/?id=LIBGSF_1_14_26 close to the bottom).
Comment 5 Laszlo Ersek 2013-06-25 16:30:09 UTC 
Great, thanks!

Since the broken out patch didn't fix my problem, maybe this BZ should concern upgrading libgsf to 1.14.26, rather than backporting one patch.

OTOH 1.14.26 requires a higher glib2 than what's available in RHEL-6 (as you were kind enough to point out and patch the dependency as well, highly appreciated!), so any such upgrade will probably need your patch too <http://lists.nongnu.org/archive/html/qemu-devel/2013-06/msg04498.html>.

I'll try to test it as soon as I can. Thanks.
Comment 6 Laszlo Ersek 2013-06-26 10:53:56 UTC 
Turns out (see thread linked above) that updating libgsf is insufficient, msiextract (or the updated libgsf itself) would further depend on a very recent glib2 release (2.33.1). That's probably too intrusive for RHEL-6. OTOH upgrading just libgsf is useless, so closing this as WONTFIX. Thanks.
