Doesn't really change things or make them better but it makes more sense to me to use table-cell for .icon-image as well and it gets much better if you set the img alignment to bottom. What about this:

.icon-image {
display: table-cell;
line-height: 100px;
min-width: 100px;
padding: 0 .5em;
text-align: center;
}

.icon-image img {
vertical-align: bottom;
}

.icon-info {
display: table-cell;
padding: 0 .5em;
overflow: auto;
vertical-align: bottom;
width: 100%;
word-wrap: break-word;
}

or even:

.icon-image {
display: table-cell;
height: 100px;
min-width: 100px;
padding: .5em;
text-align: center;
vertical-align: bottom;
}

.icon-image img {
vertical-align: bottom;
}

.icon-info {
display: table-cell;
padding: .5em;
overflow: auto;
vertical-align: bottom;
width: 100%;
word-wrap: break-word;
}
