DESCRIPTION
While using AddressSanitizer to find memory leaks with my rom-properties shell
extension, I noticed the following leak in SambaUserSharePlugin:
Indirect leak of 112 byte(s) in 1 object(s) allocated from:
#0 0x7f4a91d291ef in operator new(unsigned long)
/var/tmp/portage/sys-devel/gcc-16.1.1_p20260613/work/gcc-16-20260613/libsanitizer/asan/asan_new_delete.cpp:109
#1 0x7b4a7be7d4ca in SambaUserSharePlugin::SambaUserSharePlugin(QObject*)
/var/tmp/portage/kde-apps/kdenetwork-filesharing-26.04.2/work/kdenetwork-filesharing-26.04.2/samba/filepropertiesplugin/sambausershareplugin.cpp:97
#2 0x7b4a7be7dd9c in QObject*
KPluginFactory::createInstance<SambaUserSharePlugin, QObject>(QWidget*,
QObject*, KPluginMetaData const&, QList<QVariant> const&)
/usr/include/KF6/KCoreAddons/kpluginfactory.h:642
#3 0x7b4a8e89101a in KPropertiesDialogPrivate::insertPages()
/var/tmp/portage/kde-frameworks/kio-6.28.0/work/kio-6.28.0/src/widgets/kpropertiesdialog.cpp:557
#4 0x7b4a8e8923cc in KPropertiesDialogPrivate::init()
/var/tmp/portage/kde-frameworks/kio-6.28.0/work/kio-6.28.0/src/widgets/kpropertiesdialog.cpp:336
#5 0x7b4a8c0ef610 in rp_show_RomDataView_dialog
src/kde/config/stub-export.cpp:234
In sambausershareplugin.cpp on line 97, m_permissionsHelper is created without
a parent object specified, and it's never deleted. The end result is
m_permissionsHelper is leaked after the SambaUserSharePlugin is deleted.
STEPS TO REPRODUCE
1. Open file properties with ASan enabled.
OBSERVED RESULT
SambaUserSharePlugin leaks m_permissionsHelper.
EXPECTED RESULT
m_permissionsHelper is deleted when it's no longer needed.

Operating System (available in the Info Center app, or by running `kinfo` in a
terminal window):
